1. Getting Started Top of Page
1.1 Logging into the PubChem Deposition Gateway Top of Page
  • New User
  • Existing User
1.1.1 New User: If you are a new user to the PubChem Deposition Gateway, you will need to create an account. We would strongly recommend that you start with a Test Account. You can proceed to create a Test Account by clicking the "Create Test Account" button.

If you already have a "Test Account" and wish to proceed to putting data into PubChem, you should create a "Deposition Account". To make a "Deposition Account", press the "Create Deposition Account" button.

1.1.2 Existing User: If you already have an account, you may login to begin using the PubChem Deposition Gateway.

Please enter your username in the text box labeled "Username:" and your password in the text box labeled "Password:", then push the "Log In" button below the previously mentioned text boxes.

If you have forgotten your password, please click "Forgot Password?". You will be prompted for your "Username". An e-mail will be sent to the primary contact for that account with further instructions on how to proceed.


1.2 Creating a New Account Top of Page

Choosing an Account Type
When creating a new account you have two types from which to choose:
  1. Test Account Type:
    A Test account allows a user to go through all the steps of uploading substance and/or bioassay data. Anyone with a valid email account can get a test account. The purpose of a Test account is to allow potential depositors to validate that their data is properly suited for submission into the PubChem Deposition Gateway, without actually putting any of the data into the public PubChem system or signing off on the PubChem deposition agreement. Any data submitted via a Test account will remain accessible for up to one week.

    For instructions on creating a Test Account, continue here.

  2. Deposition Account Type:
    A Deposition account, like a Test account, begins the deposition process by allowing a user to upload and validate substance and bioassay data. The Deposition account, however, is the only way you can finish this process to make your data public in PubChem.

    Deposition accounts require more detailed information to setup and may involve direct contact with PubChem administrators for approval. Furthermore, Deposition account users must agree to and are bound by the PubChem Deposition Agreement. This agreement gives PubChem the right to redistribute the information deposited. It is important to note that all data deposited into PubChem is covered under fair-usage and, as such, does not require the depositor to assign away copyrights or other ownership prior to PubChem deposition, i.e., the deposited data does not have to become part of the public domain.

    Organizations with multiple data collections may need multiple deposition accounts. PubChem requires a separate Deposition account with a unique username for each unique data source. If you have multiple substance collections that need to be treated independently within PubChem, you will need separate Deposition accounts for each. For example, the "NIST" and "NIST Chemistry WebBook" substance collections are both generated by the organization NIST. Note, however, that if you have one collection but many users that are allowed to make depositions, we now have a mechanism to assign multiple logins. If you are not sure whether you need multiple deposition accounts, please contact the NCBI Help Desk.

    For instructions on creating a Deposition Account, continue here.


1.2.1 Creating a Test Account
A Test account allows a user to go through all the steps of uploading substance and/or bioassay data. To setup a Test account please follow three simple steps:
  1. Fill out all form items, those denoted with a "*" are required.
  2. Press the "Register" button.
  3. Go to the URL link, typically by clicking on it in the e-mail you receive from the PubChem Deposition Gateway
After these three steps are complete, you may login and begin using the PubChem Deposition Gateway. If you do not complete Step 3 within 24 hours of completing the first two steps, you will need to start again from Step 1.

E-Mail
Before your Test Account is activated for use, an e-mail will be sent to this address with further instructions.
Notify About Submission Status Changes
This is a pull-down menu that allows you to choose whether or not you would like automated e-mails sent to you as your submission is processed or as its status changes. There is a third option for multi-user deposition accounts entitled "My submissions only" which means that you will only be mailed for submissions you have personally initiated. You can modify this notification setting in your Account Info after you login.
Password
Choose an account password. You must type the same password in the text boxes "Password" and "Confirm Password". Please commit this password to memory, as you will need it every time you attempt to login to the PubChem Deposition Gateway.

The password you provide must be at least six characters long and cannot be your username.

First Name
Your first name.

Last Name
Your last name.

Additional Information
Please type any additional information or notes in this text box.

Data Transfer Agreement
You must agree to the Data Transfer Agreement for this website, prior to receiving a PubChem Test Account. To agree, you must make sure the check box is checked.

1.2.2 Creating a Deposition Account
A Deposition account allows a user to go through all the steps necessary to put substance and/or bioassay data into PubChem. To setup a Deposition Account please follow three simple steps:
  1. Fill out all form items, those denoted with a "*" are required.
  2. Press the "Register" button.
  3. Go to the URL link, typically by clicking on it in the e-mail you receive from the PubChem Deposition Gateway.

After these three steps are complete and your information is reviewed and verified by a PubChem administrator, you may receive an e-mail notifying that you may login and begin using the PubChem Deposition Gateway. It is possible that you may be contacted by phone or e-mail by a PubChem administrator during this process. If you do not complete Step 3 within 24 hours of completing the first two steps, you may need to start again from Step 1.

Multiple Users on One Account
It is now possible to create one deposition account that contains multiple users, each having their own login and password.
  • How this works
    • Separate logins
      You can now have an arbitrary number of users each with her own password on one deposition account. No one can see the password of another user, but there is one primary user who can add and remove other users.
    • Separate deposition tracking
      For each action that a user takes, the processing history for a substance or assay deposition will record that user's id. The user who initiates a deposition, however, will remain associated with the deposition even if others work on it. The pending listing, for example, of that substance or assay deposition will show that user as the owner.
    • Joint access
      Though login and tracking is distinguished, access is not. All users from the same data source will see all of their depositions whether they initiated them or not. Users are also free to make follow-up actions on any submission from their data source. For example, if jane_doe deposits a file of substances that pass validation, juan_carlos (from the same data source) may commit the submission for publishing or for that matter may even delete it.

  • How you implement it
    If you would like to have multiple users for your data source, please follow these steps.
    1. Choose one person to be the administrator and have that person create the initial deposition account as described. If you already have a deposition account and would like to add users, skip to the next step.
    2. Your administrator must login and goto the Account Info > Contacts tab and click on the Add Contact View on the left side. Fill out this form for each additional user. You can have the user enter her password while the administrator is present or the admin can enter a temporary and the user can change it afterwards.

2. PubChem Deposition Gateway Top of Page

Uploading and managing depositions is fairly straightforward. First, you will need to familiarize yourself with the required file format documentation and review the PubChem Deposition Gateway help documentation.

Essentially, the deposition process consists of uploading an appropriately formatted PubChem data file. The file contents are subjected to several stages of validation. After all validation checks are complete, an e-mail may be sent notifying you to review your submission.

After your review, PubChem Deposition Gateway users with a Deposition Account may "Commit" their successfully validated data. Typically, your committed data will be made available in PubChem within two days. It is possible, however, that your committed data availability may be delayed, especially if you are notified that there is further action required on your behalf.

The PubChem Deposition Gateway provides the means for you to manage and review your depositions. You may delete or review prior submissions. If you have a Deposition Account, you may also generate reports of prior submissions and retrieve the PubChem Substance identifiers (SID) for your successful depositions.

When you enter the PubChem Deposition Gateway, you will see, immediately below the heading "PubChem Deposition Gateway", a navigation bar with various tabs and icons. You may click on the tab text or icons at anytime for navigation. These tabs are: At the time of login, you will always default to the "Welcome" tab.

2.1  Home Tab
Clicking the "Home" Tab gives you a screen listing short descriptions of the main activities from which you can choose:
  • Substances - Deposit new or resume suspended submissions
  • Assays - Deposit new or resume suspended submissions
  • Account Info - Review your account information/preferences
Please note that you may also use the main navigation bar tabs with identical labels as the links, as they perform the same function.

2.2  Substances Tab
Clicking the "Substances" Tab puts you onto the substance welcome page.
2.2.1  Substances > Welcome Tab
The substance welcome page lists the main substance deposition activities from which you can choose:
  • New - Upload a file of chemical structure records for deposition to PubChem
  • Pending - Resume unfinished depositions
  • Deposited in PubChem - Access previous depositions in PubChem
Please note that you may also use the main navigation bar tabs with identical labels as the links, as they perform the same function.

2.2.2  Substances > New Tab

Clicking the "New" Tab gives you a screen that allows you to upload a file into the PubChem Deposition Gateway. Prior to submitting any files, please review the following document describing the allowed format of files deposited.

The format of the file you upload is expected to be in SD File format. Each substance in the SD file must have a unique registry ID in the appropriate SD field. A description of the allowed and required SD fields is available . For examples of suitable SD files for deposition, see this SD file.

Press the "Browse..." button to select a file to upload to the PubChem Deposition Gateway. After selecting a file, provide comments in the "Comments:" text box that will help you track this deposition and, perhaps, provide useful information to the PubChem Deposition Gateway administrators. Please remember to press the "Submit" button after you have selected the appropriate file and provided necessary comments. When the file transfer is complete, you will be transferred to "Pending" displaying this submission.

Please note that the file you upload to the PubChem Deposition Gateway may be compressed. Compressing your file may substantially reduce the time it takes to transfer your data. We support files compressed using the "gzip" compressor. Please note that we do not support "zip" or "bzip2" compressed files.

When substances are deposited in PubChem, the depositor category will be assigned to all substances. Based on the depositor's category, users can expect to find additional category-specific information either on the PubChem substance summary page or on the depositor's site.

The different categories and their descriptions are the following:

StatusMeaning
Biological Properties Depositor provides information about the biological properties of a substance or compound
Chemical Reactions Depositor provides information about the reactivity, synthesis, or known reactions of a substance or compound
Imaging Agents Depositor provides information about the contrast agent or imaging agent used in, for example, MRI's
Journal Publishers Depositor is a journal publisher and has articles published about a substance or compound
Metabolic Pathways Depositor provides information on the metabolic pathways involving a substance or compound
Molecular Libraries Screening Center Network Depositor is part of the NIH Molecular Libraries Screening Center Network (MLSCN)
NIH Substance Repository Depositor is an NIH Molecular Libraries Small Molecule Repositor servicing the MLSCN
Physical Properties Depositor provides information about the experimental physical properties of a substance or compound
Protein 3D Structures Depositor provides information about the experimental 3-D structure of a substance or compound
Substance Vendors Depositor is a seller of a substance or compound
Theoretical Properties Depositor provides information about the theoretical properties of a substance or compound
Toxicology Depositor provides information about the toxicological properties of a substance or compound

2.2.3  Substances > Pending Tab
This tab gives you a list of your unfinished or recently added depositions to PubChem.

A "Filter by Status" pull-down menu allows you to filter your submissions by multiple criteria. By default, all submissions, "Any Status", are shown. The other filter criteria are:
  1. Failed - Submissions that failed validation checks at any processing stage
  2. Processing - Submissions being validated by the PubChem System
  3. Commit Required - Submissions validated by PubChem and awaiting your Commit
  4. Committed - Submissions committed by you awaiting PubChem approval
  5. Rejected - Submissions rejected by a PubChem administrator
  6. Approved - Submissions approved by a PubChem administrator
  7. Deposited in PubChem - Submissions now publicly available in PubChem
Below the "Filter by Status" is a summary line denoting the number of submissions meeting the filtering criteria. Furthermore, the summary line includes the total count of records parsed, substances standardized, and processing (error, warning, and informational) messages. Please note that substances standardized count refers to chemical structures considered valid by PubChem.

The pending submission table columns provide a summary of each deposition:
ID
The submission id number used in the Deposition Gateway.

Submitter
The person who initiated this submission. This is only present for accounts which have multiple users.

Started
The date and time on which you initiated your submission.

Status
Summary of the submission status denoted by a graphical depiction. Each dot represents a particular phase of the submission process. Green dots denote success. Red dots denote failure. Blue dots denote an uninitiated submission phase. Yellow dots denote a submission phase in-progress. When all the dots are green, your deposition is in PubChem.

File
The name of your uploaded file.

Records
The total number of substances uploaded in this submission.

Curator
The person handling your deposition (typically assigned after you have committed it). Unlike the other fields, this field points to the curator's email address.
The pending submission table column headings can be used to sort the table. For example, clicking on "Started" will sort the table by date. Clicking the "Started" column header for a second time will reverse the order of the sort.

Clicking on any row will put you in the Validation Summary View under a dynamically-created Pending <Submission-Id> Tab for the corresponding submission.

2.2.4  Substances > Pending <Submission-Id> Tab
This tab is created when viewing any details for a particular submission in process.

A. Submission Page Overview
In this section the basic elements common to all views for a particular submission will be explained.
Submission Page Overview
To Proceed box
On the left side below the tabs, this box gives a hint for the next
step needed to push your submission forward towards deposition.		 Submission To Proceed Box

Progress Meter
In the middle below the tabs, this meter gives information about the
current state of the deposition.		 Submission Progress Meter


The progress meter shows a graphical timeline of your deposition. The main stages of the process are written above the meter. Each step may have multiple actions that must be completed before going on to the next step. The specific action that the system is undergoing at the moment is written immediately below the meter.

The Summary information below the Progress Meter provides the Submitted timestamp of your upload and a summary of processing statistics. Critical statistics will be highlighted in red.

The phases of the submission process, in order, are:
  1. Submit
  2. Standardize
  3. Approve
  4. Deposit in PubChem

Submit
The Submit processing phase includes your initial file submission upload and the system's syntax validation of your submission. If your file is incorrectly formatted, you can consult the appropriate Views for more information, but you must fix and resubmit the file in order to proceed.
Successful completion of this phase automatically initiates the next processing phase.

Standardize
The Standardize processing phase performs several actions on the data. It begins by examining the data provided by your submission. The chemical structure information is validated and standardized for use within PubChem. Your textual information is also examined and validated. Substances that fail this standardization process will not be assigned a CID. It is possible that this phase will fail for some poorly formatted files. If your substances do not have chemical information available, then it is expected and normal that they will "fail" Standardization. This is the only action in which failing may not require your intervention. In addition to this action, the Standardize phase also includes additional validation checks.

The first validation action crosschecks your submission with other submissions you have within the PubChem Deposition Gateway. These crosschecks detect duplicate registry ID's and duplicate structures.

The second validation action crosschecks your submission with previous submissions already deposited in PubChem. These crosschecks detect duplicate registry ID's and duplicate structures.

The Standardize phase is initiated automatically after successful completion of the Submit phase.

Approve
The Approve processing phase is available only to deposition account users and must be initiated by the depositor by pushing the "Commit" button. This phase cannot be initiated if any previous processing phase has failed.

The Approval phase is completed by a PubChem registrar. The registrar examines the deposition for completeness and, after a brief review, either approves or rejects the submission for addition to PubChem. A PubChem registrar may contact you by phone or e-mail concerning your submission.

If the PubChem registrar approves the submission, the final Deposit in PubChem phase is initiated automatically.

Deposit in PubChem
The Deposit in PubChem phase is the final processing stage, where your submission is actually loaded into the PubChem system. A report, which you may download, is generated from this loading process. After your data is successfully loaded into PubChem, the data will usually become publicly accessible within two business days.

Views box
On the bottom left side, this box indicates the current view and
shows other available views appropriate for the current state of the
deposition.		 Submission Views Box


  1. Validation Summary View
  2. Validation Details View
  3. List All View
  4. List Failed Standardization View
  5. PubChem Structure Preview View
  6. History View

A. Validation Summary View
Clicking the Validation Summary View provides a summary table of the unique message categories encountered during your deposition. The summary table columns are:
  1. Severity - Submission message severity
  2. Category - Submission message category
  3. Count - Count of submission messages of the category type
  4. Phase - Submission processing phase where the message was encountered

The column headings can be used to sort the table. For example, clicking on "Category" will sort the submission table by category. Clicking the "Category" column header a second time will reverse the order of the sort.

Clicking on text in a row will transfer you to the Validation Details View filtered to show you only those records with that particular message category corresponding to the row you click.

B. Validation Details View
Clicking the Validation Details View provides a detailed list of all messages generated by the PubChem processing. The details table columns are:
  1. Severity - Submission message severity
  2. Category - Submission message category
  3. Message - Submission message
  4. Record - SD file record number
  5. Line - SD file line number that generated the message
  6. Phase - Submission processing phase where the message was encountered
The column headings can be used to sort the table. For example, clicking on "Message" will sort the submission table by category. Clicking the "Message" column header a second time will reverse the order of the sort.

To filter the details table by category of validation message, return to the Validation Summary View. To filter the details table for a substance, proceed to the List All View.

Clicking on any text in a row will, typically, spawn a new browser window. Depending on the context of the message, this window will display different information. If the message is in the context of the records you uploaded, the window may display the SD file record number, a depiction image of the SD file record, and the uploaded SD file record, prefixed with the SD file line number. Alternately, if the message context refers to collision with a different submission, you will view the submission record from that deposition.

C. List All View

Clicking the List All View provides a summary view of the processed data records with counts of messages associated with that record. The processed records table allows for rapid navigation to particular records in your submission. The standardized table columns are:
  1. Record - Sequential record number of your submission
  2. Depiction - Thumbnail depiction for the submitted substance
  3. RegID - Your unique registry ID for the substance
  4. Comments - Your comments provided at the time of submission.
The column headings can be used to sort the table. For example, clicking on "RegID" will sort the table by registry ID. Clicking the "RegID" column header a second time will reverse the order of the sort.

Clicking on a row will transfer you to the PubChem Structure Preview View showing the substance record corresponding to the row you click.

D. List Failed Standardization View

In the case that you have substances which have failed standardization, an extra View will appear to isolate those failed substances. Clicking the List Failed Standardization View displays the same information as the List All View filtered for failed records only.

Please note that if your substances do not have chemical information available, then it is expected and normal that they will "fail" Standardization.

As with the List All View, clicking on a row will transfer you to the PubChem Structure Preview View showing the substance record corresponding to the row you click.

E. PubChem Structure Preview View

Clicking a particular substance record in the List All View or the List Failed Standardization View provides a summary view of complete individual substance records. The display of your substance closely resembles how the submitted data will appear in the PubChem Substance Summary CGI. The URL links are available on this page so you can test the links back to your website to verify that the URL's work as intended. Additionally, you can see how PubChem processing affects the data you have provided.

The "Compound Displayed" pull-down menu allows you to toggle between the "PubChem" processed structure and the submitted "Deposited" chemical information, when such information is provided. If your substance has multiple components or is ionized, you may have additional views of unique component or neutralized forms of your substance.

A navigation bar is available to step through your submitted substances:
  • First Button Transfers you to the first substance
  • Previous Button Displays the previous substance
  • Next Button Displays the next substance
  • Last Button Transfers you to the last substance
  • Back Button Transfer you to the "Standardized" Tab
Additional buttons are available to jump to different parts of the Substance Summary view:

Various export buttons are available to allow you to examine the PubChem data records generated for your substance in ASN.1, XML, and SDF file formats.

F. History View

Clicking the History View displays a detailed chronology of the processing phases for the submission. The history table columns are:

  • Originator - Your unique registry ID for the substance
  • Date - Timestamp when a particular stage has completed
  • Stage - Graphical depiction of the stage
  • Comments - Processing stage specific comments.
The column headings can be used to sort the table. For example, clicking on the column "Date" will sort the submission table by date. Clicking the "Date" column header a second time will reverse the order of the sort.

Action buttons
  • Original File Icon
  • Save Report Icon

2.3  Assays Tab
Clicking the "Assays" Tab puts you onto the assay welcome page.

2.3.1  Assays > Welcome Tab
The assay welcome page lists the main assay deposition activities from which you can choose:
Please note that you may also use the main navigation bar tabs with identical labels as the links, as they perform the same function.

Choosing an Assay Action
Perhaps the biggest change in how the Deposition Gateway handles assay depositions is that now you choose from four distinct assay actions whenever you want to affect your public data in PubChem. The first choice you must make is whether you want to create a new assay or modify one of your existing PubChem assays. If you want to modify a PubChem assay, you have three further choices of possible modifications:
  1. New assay
  2. Add/Change data (Modify)
  3. Alter description (Modify)
  4. Replace assay (Modify)
You can leave your unfinished assay action at any time and return later to find it under the Pending tab. Once your action becomes part of PubChem, it will be removed from the pending table. If you'd like to make further modifications, you will choose it under the Modify tab in your list of PubChem assays.

2.3.2  Assays > New Tab
  • Understanding Basic Concepts
  • New Assay Deposition Overview
  • New Tab Description

Clicking the "New" Tab is the starting point for creating a new biological assay deposition in the PubChem Deposition Gateway as a means of making your data public in PubChem. We will now have a brief overview of the assay deposition process. If you would like to skip to the specific explanation of the New Tab, click here.

Understanding Basic Concepts

Prior to depositing biological assay data into PubChem, it is important to understand the nomenclature we use so that you and we are referring to the same elements. Please read the following paragraph to make sure we are clear on a few terms: Substance, Assay Description, Assay Data, and Activity Summary.

An Assay Description refers to the protocol and parameters of an assay, which can only be defined once.  Assay Data are the actual results; as long as they follow the protocol of the Assay Description, Assay Data on new substances can be continually added.  A Substance is the stuff being tested; typically it is what is in an assay plate well. A Substance can be a discrete chemical entity, e.g. aspirin, or a complex mixture, e.g. a plant extract. If you think the material in two assay plate wells is the same, we ask that you refer to it as the same Substance with a single Activity Summary. If you think material in two wells differ, please refer to them as two distinct Substances, hopefully with different chemical structures (or different mixtures), and surely with distinct Activity Summaries. It is of course very common to do replicates across different batches and salt forms of a Substance when you believe the salt form to be irrelevant to activity. Your data, however, must be reduced to a single Activity Summary per substance that is submitted as an integer value: "inactive" - 1, "active" - 2, or "inconclusive" - 3 (if there are indeed contradictory replicates). In this way, your results will be much more accessible and understandable to users through the various searching and graphing functions of the PubChem Bioassay system.

New Assay Deposition Overview

There are several steps in a new assay submission that must be followed sequentially to complete the process:
(Submit Substances) > Create Description > Add Data > Approve > Deposit in PubChem
  • Submit Substances
    This step is not mentioned on the Progress Meter but is a prerequisite for assay depositions. Before depositing assay data please make sure that all substances tested in your assay are deposited in PubChem and have SIDs assigned. In your assay data file you can refer to substances with either PubChem-assigned SIDs or your own unique RegIDs, but in order to complete the assay deposition we must be able to find a valid PubChem SID for each substance. Details on substance deposition are given in the description of the Substances tab.

  • Create/Edit Description
    An Assay Description defines the results you wish to report. You have the ability to provide a detailed description of the assay being performed. There are separate sections to provide a description, protocol, comments, annotated cross-references, result definitions, and restrictions on allowed data values. The description for a particular assay must be input before the corresponding data can be uploaded for the sake of validation. Note that once an assay description is defined, you can continually add results tested on new substances.

  • Add Data
    Once your description has been entered and verified, you upload your appropriately formatted assay data file. The data will be parsed and validated. All issues ranging from informational to critical errors will be reported back to you. If there are critical errors, you must fix them and resubmit your data file by first deleting the data file with errors.

  • Approve
    If your data has no critical errors, it will pass to the Approve step. Your deposition will be loaded into a Preview Database. Once this is complete, you will receive an automated email containing a link to the Preview Assay. At that point, you also can access the preview by clicking on the Preview button for your pending assay.

    The Preview will show you how your assay will look in PubChem. This is the last opportunity to validate your data before you commit it. If you confirm that your assay action should be public in PubChem, click on the "Commit" button and a reviewer will inspect and approve it. At this stage if you find an error, you must contact the reviewer for any possible "emergency" assistance as you have already approved it for deposition. Once Deposited in PubChem, additional changes can be made by starting a Modify action.

  • Deposit in PubChem
    Once your data is approved it goes through several final validation steps and is uploaded to PubChem. Due to loading and synchronization schedules of the PubChem database servers, a moderate delay should be anticipated. After approval, the data typically will become public in PubChem within 24 hours.

New Tab Description
Click on the New tab under the Assays tab to begin uploading a bioassay into the NCBI PubChem Deposition Gateway. If you are returning to resume working on a new assay deposition, please look under the Pending tab to find it.

Progress Meter
Just under the rows of tabs in the middle of the page is the progress meter.
New Assay Progress Meter
The progress meter shows a graphical timeline of your deposition. The main stages of the process are written above the meter. Each step may have multiple actions that must be completed before going on to the next step. A brief explanation of each step can be found in the previous section.

Input Assay Description
Once you have read this section and are ready to input your description, begin by choosing your method of input: Prior to uploading or entering anything, please review this help document describing the allowed file formats. Once the bioassay has been deposited, all parts of it must pass an automated validation procedure without errors in order to be accepted into PubChem. If you need to make changes to your assay after deposition to PubChem, please refer to the "Modify" tab.

An Assay Description defines the results you wish to report. You have the ability to provide a detailed description of the assay being performed. There are separate sections to provide a description, the protocol, comments, the activity outcome method, target data, annotated cross-references, result definitions, and restrictions on allowed data values. The description for a particular assay must be input before the corresponding data can be uploaded for the sake of validation. Once your assay is defined in PubChem with an initial set of data, you can continually add results tested on new substances for the same assay description by going to the "Modify" tab.

Descriptions can be input by filling in the form on the webpage, by uploading an XML file or by using one of your existing PubChem assays as a template. You must define at least one result definition (TID).  To see an example description, download and upload this example file.

Fill in Form

Enter each of the required and optional fields necessary to describe the assay (as described below) into the corresponding boxes. Once the boxes are completed, click on "Create" to enter the data or "Cancel" to start over.

Upload Assay Description XML File
Click on "Browse", choose the appropriate XML or gzipped XML file conforming to the PubChem standard for the PC-AssayDescription specification. Here is an example file.

Use PubChem Assay as Template
Choose one of your existing PubChem assays from the pulldown menu and click on "Load". This option is only for convenience; the assay you are creating will have no special link to the assay you chose for a template. You will be required to create a new RegID and Name for your new assay as with the other two input methods.


Assay Description Fields
The description of the assay defines the assay purpose and parameters. Fundamentally, the Assay Description defines the "columns" that are populated by the Assay Data "rows". Each "column" is assigned a result type identity (TID) in the Results Definition section. The Assay Data uploaded later must be reported in the same order as the TIDs defined in the Assay Description. Additionally, the Assay Data must be consistent with the Assay Description TID definitions.

The description of an assay consists of nine parts: External Assay RegID, Name, Description, Protocol, Comments, Activity Outcome Method, Target Data, XRef Data and Results Definition.
External Assay RegID
The external assay identifier assigned by the depositor. This must be unique amongst your other PubChem assays.

Name
A short, informative name of the assay for display purposes.

Description
A definition of the assay purpose and parameters.

Protocol
The assay protocol description must be provided here.

Comments
Any comments on the assay can be provided here.

Activity Outcome Method
You must classify the activity outcome method of your assay here. Choices include:
  • Screening assay - Single Concentration Activity Observed:
    Activity outcome was defined based on the percentage of inhibition from test at a single dose
  • Confirmatory assay - Concentration-Response Relationship Observed:
    Activity outcome was defined based on EC50/IC50 values and so forth, derived from dose response curves following testings with multiple concentrations
  • Summary assay - Candidate Probes/Leads with Supporting Evidence:
    An assay which summarizes information from multiple assays
  • Other - An assay which does not fall into the above categories
Active Concentration TID
For Confirmatory assays only, an additional pulldown menu appears requiring the indication of which of your TIDs provides active concentration summary. Such a summary might be reported as the concentration which produces 50% of the maximum possible biological response such as IC50, EC50, AC50, GI50 etc. or by reporting constant parameters such as Ki, that based on which the activity outcome of your assay is called. Please choose the column number and TID name as found in your Results Definition list.

Target Data
For any assay designed to identify chemicals interacting with a protein target, such as enzyme inhibitors, please add the identifier of the target molecule - either a valid nucleotide (DNA or RNA) or protein NCBI GI.

Please note that for such assays you should not add an additional XRef protein link. In the opposite case, in which it is only known that an assay is identifying modulators that affect some biological processing, for example, to identify compounds affecting certain protein expression, it is appropriate to identify a protein with an XRef link (described in the next section) and not with Target data.

XRef Data
External data to help describe the assay. (Examples: Reference URLs to go to the source database/assay, to PubMed, to GenBank, etc.)

Attention: for XRef protein links please see the previous section on Target data to determine whether you should make an XRef protein link or fill out Target data information. You should not do both.
Type
Choose from a list to classify the data type.

Value
The actual data, such as a URL or an identifer.

Annotation
A comment to describe the XRef data.
Results Definition
Column definitions for the assay results that will be uploaded in the next step. Use the "Add" and "Remove" buttons to create the same number of results definitions as there are columns in the assay data. For each definition there are the following fields:
Name
The name of a result. Keep this short, but informative.

Type
The result type must be a Float, Integer, Boolean or String.

Unit
Various units are available to choose from if appropriate.

Description
More description to the result beyond its name.

Constraint
Limits on the range of accepted values for integers and floats.  The more limits that can be introduced, the more validation can be performed on future data added to the assay.  A minimum and/or maximum can be specified or specific acceptable values can be specified.
Set of Values
Individual allowed values for integer type only.

Minimal Value
A single number to specify minimum possible allowed value for integer or float type only.

Maximal Value
A single number to specify the maximum possible allowed value for integer or float type only.

Range
A Minimal Value and a Maximal Value.
Attribute: Tested Concentration
If box is checked, the micromolar concentration at which this result was tested. This concentration attribute indicates that the readout under this test result field is biological concentration-response data, the attribute provides the value of the tested concentration in micromoles.

Attribute: Concentration-Response (CR) Plot Labels
Use this attribute to track concentration-response series for confirmatory assays only.

If the Tested Concentration attribute for a result definition is filled in, then the optional "CR Plot Labels" menu appears for that TID. By default, only one CR label appears in the menu but the user can add labels by visiting the "Concentration-Response (CR) Plot Labels" section at the bottom of the description page.

Multiple labels are useful for assays with multiple series of data and tested concentrations. For each CR Plot Label series there should be at least three activity data points with tested concentration attributes set.

Collecting this information allows PubChem to annotate and track the concentration-response series reported, and will facilitate the development of new features such as drawing dose-response curves upon request of PubChem users.

Create your Description

Once you have finished entering your description and verified that it is accurate, click on the "Create" button. If the system finds no errors with it, it will become a pending assay in the Deposition Gateway and you will be routed to a dynamically-created tab entitled "New assay assay-id" where the assay-id is an identifer to keep track of the assay while it is in the Deposition Gateway. To continue reading about the next step in the new assay deposition process, click on Add Data. Otherwise, we will now discuss the next Tab under the Assay Tab, the Modify Tab, which allows for various operations to existing PubChem assays.

2.3.3  Assays > Modify Tab
Clicking on the "Modify" tab routes you to a Modify "Welcome" tab starting on a third row of tabs.

2.3.3.1  Assays > Modify > Welcome Tab
Assay Modify Welcome Tab
The modify assay welcome page lists the three types of modifications you can make on one of your existing PubChem assays:
  • Add/Change Data - without description change
  • Alter Description - with changes such as fixing a typographical error or adding XRef data like a URL (no data can be added)
  • Replace Assay - to make a significant change such as adding/removing/modifying a result column (all data must be resubmitted to replace existing data)
2.3.3.2  Assays > Modify > Add/Change Data Tab
This tab is the starting point for the most common type of modification to an existing PubChem assay: adding or changing data results. With this mechanism you can add new data results, replace selected data results, or remove data results that are no longer valid.

Note that any duplicated substance (SID/RegID) test results for a given assay (whether in the same data file or not) will be archived in PubChem. Only the most recent one will be available for searching.

If you are returning to resume working on an Add/Change Data action, please look under the Pending tab to find it.

To revoke test results please submit a csv file with the following format. If your intention is to revoke the actual substance, you must first revoke it from any assays where it is a test result, then revoke it from the Substancestab.

Progress Meter
Just under the rows of tabs in the middle of the page is the progress meter.
Add Data Progress Meter
The progress meter shows a graphical timeline of your deposition. The main steps of the process are written above the meter. These steps to Add/Change Data to a PubChem assay must be followed sequentially to complete the process:
(Submit Substances) > Add Data > Approve > Deposit in PubChem
Each step may have multiple actions that must be completed before going on to the next step. Click on a step for a brief explanation.

Submit CSV Data File
Pick the PubChem assay you wish to modify from the pull-down menu, click on "Browse" to choose your CSV data file, and click "Submit". Note that if you are already modifying this assay in a pending action, you will not be able to proceed. When it loads, an Add/Change Data <Assay-Id> Tab tab will be created for you for the next step of validating your data. Also note that for this action you can only view the description, but can not modify it.

2.3.3.3  Assays > Modify > Alter Description Tab
This tab is the starting point for making small changes to your description. Typical examples of changes you can make here are fixing typographical errors in the Description/Protocol/Comments sections and adding XRef data, like a URL to your website. No data can be added in this action. You can not change the meaning or number of Results columns because such changes invalidate the assay's existing data. If you must do that, please see the Replace Assay tab.

If you are returning to resume working on an Alter Description action, please look under the Pending tab to find it.

For this action the revision of your PubChem assay will be incremented, but the version will remain unchanged. While in the Deposition Gateway, the pending assay will show a blank revision since it is being modified.

Progress Meter
Just under the rows of tabs in the middle of the page is the progress meter.
Add Data Progress Meter
The progress meter shows a graphical timeline of your deposition. The main steps of the process are written above the meter. These steps to Alter Description of a PubChem assay must be followed sequentially to complete the process:
Edit Description > Approve > Deposit in PubChem
Each step may have multiple actions that must be completed before going on to the next step. Click on a step for a brief explanation.

Choose existing Description to modify
Pick the PubChem assay you wish to modify from the pull-down menu and click "Load". Note that if you are already modifying this assay in a pending action, you will not be able to proceed. When it loads, an Alter Description <Assay-Id> Tab tab will be created for you for the next step of modifying your description. Remember that for this action you can not submit data.

2.3.3.4  Assays > Modify > Replace Assay Tab
This tab is the starting point for making significant changes to your description. Typical examples of changes you make here are adding or removing a Results column or changing the data type of a Results column. For this action you must resubmit all of your data results along with your description change. If an existing data result is not resubmitted with this action, it will no longer be available in PubChem when the change is made public.

Special note: This is a powerful action that should be used as a last resort. It is your responsibility to maintain consistency with what this assay currently means in PubChem. Think of PubChem users who expect that the existing data to this assay may grow in number, but will not change in definition. Even here you can not modify the External Assay RegID. If this is what you want to do, please consider creating a new assay.

You can not use this action to only make small description changes, like adding a URL XRef. To do that please see the Alter Description tab. However, if you have a modification for a result's name or description which would invalidate existing PubChem test results, then this is the correct action.

If you are returning to resume working on a Replace Assay action, please look under the Pending tab to find it.

For this action the version of your PubChem assay will be incremented and the revision will be reset to zero. While in the Deposition Gateway, the pending assay will show a blank for both version and revision since they are being modified.

Progress Meter
Just under the rows of tabs in the middle of the page is the progress meter.
Add Data Progress Meter
The progress meter shows a graphical timeline of your deposition. The main steps of the process are written above the meter. These steps to Add/Change Data to a PubChem assay must be followed sequentially to complete the process:
(Submit Substances) > Edit Description > Add Data > Approve > Deposit in PubChem
Each step may have multiple actions that must be completed before going on to the next step. Click on a step for a brief explanation.

Choose existing Description to modify
Pick the PubChem assay you wish to modify from the pull-down menu and click "Load". Note that if you are already modifying this assay in a pending action, you will not be able to proceed. When it loads, a Replace Assay <Assay-Id> Tab tab will be created for you for the next step of modifying your description. Remember that this action will replace all of this assay's existing PubChem data.

2.3.4  Assays > Pending Tab
This tab gives you a list of your unfinished or recently added depositions to PubChem.  To resume working on a given assay (or simply to view its detailed information), click on one of the fields in its row. If you have not yet started on your desired assay operation, please choose from the New or Modify or tabs as appropriate.

Please note that once your deposition has been successfully uploaded to PubChem, you will view it in PubChem and not in the Deposition Gateway. The successful deposition will remain listed here for a short time and then you can see a history of the operation under the Deposited in PubChem tab. If you'd like to make further modifications, you will choose it under the Modify tab in your list of PubChem assays.

Also note that unfinished assay actions will be deleted from the Deposition Gateway after one month of inactivity. This will have no affect on PubChem and only means that you will need to re-enter your description and/or data as appropriate.

The column headings can be used to sort the table. For example, clicking on the column "Action" will sort the table by the type of action. Clicking this column header a second time will reverse the order of the sort.

Assay
The temporary id assigned to track substances while in the deposition system.

PC-AID (Ver.Rev)
The permanent assay id number assigned once the assay is accepted into the PubChem system. Note that this identifier will only be non-zero for one of the Modify operations to one of your existing PubChem assays.

"(Ver.Rev)" refers to the Version and Revision of your PubChem assay. These will also be blank if the PC-AID has not yet been assigned. In addition, if the modify operation you are undergoing will have the affect to change either the Revision or the Version and Revision, then the respective place holders will show a "-" to indicate they are being updated.

Action
One of four types of actions you can perform on PubChem assays.
  1. New assay
  2. Add/Change data (Modify)
  3. Alter description (Modify)
  4. Replace assay (Modify)

Status
The current step of the assay in the deposition process.

RegID
The substance registry id as supplied by the depositor.

Name
A descriptive name of the assay.

Date
The date and time on which your assay operation began.

Curator
The person handling your deposition (typically assigned after you have committed it). Unlike the other fields, this field points to the curator's email address.

2.3.5  Assays > <Assay-Action> <Assay-Id> Tab
  • Assays > New Assay <Assay-Id> Tab
  • Assays > Add/Change data <Assay-Id> Tab
  • Assays > Alter description <Assay-Id> Tab
  • Assays > Replace assay <Assay-Id> Tab
This tab is created when working on and viewing any details for a particular assay in process. It's name tells you the type of action you are performing and the temporary id assigned to track the assay while in the deposition system. Please note that this is different than the permanent PubChem-AID.

Page Layout

To Proceed box
The To Proceed box on the left side below the tabs gives you a hint of what you must do next in order to advance your deposition to completion.

Views
The Views box on the lower left side lets you pick appropriate informational views of your deposition relevant to the current stage of the process. We will now go through a detailed explanation of the various views available. Some views are unique to one step of the process, some are unique to one of the four assay actions, and others are common (for example "View Description"). Please find the View you have questions about and read more about it.
Add Data View

This is the View where you upload your assay data file in CSV format. Click on "Browse" to choose your CSV data file, and click "Submit". If you are trying to find this view and already have data uploaded in your deposition, first click on Delete Data, then you will see this View. Also note that this View is not appropriate for the Alter description action as it does not allow data uploads.

The data will be parsed and validated against the description information to find all relevant issues with the data.  If there are any errors, you must resolve them before the data can be committed into PubChem.

CSV formatted assay data

The PubChem BioAssay Deposition System allows the use of CSV (Comma Separated Value) formatted data files for assay data deposition. The CSV column ordering for the first seven columns is fixed and must be exactly as documented below.  Beyond that, there must be a column for each result (TID) defined in the description.

The best way to get familiar with this format is to click on the "CSV Template" link (in the Add Data View only) to download a CSV template file using the Assay Description that you have already entered.  This is a guide so that you can cut and paste your data into this CSV file while strictly maintaining the correct number of columns.  For fields without data there will be nothing but consecutive commas.  We also have an example CSV file with data. Your CSV file must either have no column headers or these automatically generated headers; any deviations will cause errors.

Note that any duplicated substance (SID/RegID) test results for a given assay (whether in the same data file or not) will be archived in PubChem. Only the most recent one will be available for searching. Also note that at the moment the scheme whereby depositors are able to split their assay data into several data files and load them separately is not available. We hope to have a mechanism to load multiple files as a single deposition, but for now please combine them prior to uploading.

The following fixed columns are expected in your CSV file. Don't put anything in optional fields for which you have no data.
Column headers and their order in the data file(s) should exactly match names and order of the result definitions (TIDs).
Column 1: PUBCHEM_SID
If you have previously deposited your Substance description into PubChem, you may use your Substance identifier (SID) assigned by PubChem. This must be an unsigned integer value and, in nearly all cases, your organization must have deposited the Substance associated with this SID. Optionally, you may choose to use "Column2" instead, to provide your own Substance identifier, and, if you do, you must set this column value to be "0". If you have not previously deposited your Substance descriptions into PubChem, you must, at a minimum, have these in the PubChem deposition system prior to uploading Assay Data. If you have Substance descriptions in the PubChem deposition system, you may have Assay Data refer to these by setting the value in this column to "0" and use "Column2" to provide your identifier to this Substance.

Column 2: PUBCHEM_EXT_DATASOURCE_REGID
You may use your own identifier for Substance descriptions previously loaded into either PubChem or the PubChem deposition system. If you provide a value in this column, you must set the value in "Column1" to "0" or leave it blank.

If you choose to identify the Substance for which you are providing data using "Column1", please leave this column blank.

Column 3: PUBCHEM_ACTIVITY_OUTCOME
The Activity Summary for every Substance has two parts, the outcome and the score. The outcome for each Substance is reported as an integer value in this column and must be one of three different values:
1 - Substance is considered inactive
2 - Substance is considered active
3 - Substance activity outcome is inconclusive
4 - Substance activity outcome is unspecified

Column 4: PUBCHEM_ACTIVITY_SCORE
The Activity Summary for every Substance has two parts, the outcome and the score. The score for this Substance is reported in this column and must be an integer value, where larger values are more active and smaller values are less active. Please make sure your scores are on a linear scale because that's how they will be interpreted. We encourage depositors to consider using the range 0-100, although values larger and smaller are allowed. The score values are used to allow PubChem users to partition, sort, and profile Assay Data results within and between biological assays.

Column 5: PUBCHEM_ACTIVITY_URL
An URL may optionally be provided for Assay Data reported for this Substance in this column. This URL will be provided within PubChem displays to allow a PubChem user to link to your website, where you may choose to provide additional information or interfaces to your Assay Data, for example, dose-response curves, replicate data, etc.

Column 6: PUBCHEM__ASSAYDATA_COMMENT
Your textual annotation and comments may optionally be provided for Assay Data reported for this Substance in this column.

Column 7: PUBCHEM__ASSAYDATA_REVOKE
When you submit the data you must leave this blank or put a value '0' in this column. You may optionally suppress Assay Data for this Substance by putting a value of "1" in this column. In this case, leave all other columns blank except for Column 1: PUBCHEM_SID.  Suppressing Assay Data does not delete data from PubChem, rather it eliminates all references and links to this information; however, all pre-existing links to this information will still function and a disclaimer will be displayed specifying this data is revoked.

You may un-revoke Assay Data for a Substance by depositing either the same or new data for this Substance. Do not revoke and submit the same substance in the same file.

Columns 8 and higher (one column per TID): PUBCHEM_ASSAYDATA_VALUE
All remaining columns are an order dependent one-to-one correspondence between the result definitions (TIDs) defined in the associated Assay Description. All defined "columns" must be present; however, values are optional in individual fields. Consult the auto-generated CSV template file with your description information to see the layout.
Validation Summary View
Display issue categories related to the parsing and validation of your assay data.  This view shows the general types of issues found in processing the data including errors, warnings and info.  If errors are found, they must be resolved before the data will be accepted into PubChem.  Warnings and info issues do not have to be resolved, but often indicate something that should be adjusted.
N
Issue count.

Severity
Issue type: Error, Warning or Info.  All Error issues must be resolved.

Category
A short description of the issue.  For greater detail, go to the Validation Details View.

Count
The number of instances of this issue found.
Depositors are able to modify/change their uploaded CSV file by uploading a new one.

Validation Details View
Display all instances of issues related to the parsing and validation of your assay data.  This view lists a line for each issue found in processing the data including errors, warnings and info.  This list can be very large in some cases, so it is best to begin with the Validation Summary View.  If errors are found, they must be resolved before the data will be accepted into PubChem.  Warnings and info issues do not have to be resolved, but often indicate something that should be adjusted.
N
Issue count.

Severity
Issue type: Error, Warning or Info.  All Error issues must be resolved.

Category
A short description of the issue.

Message
The detailed message for this instance of the issue.

Data Row
The record number from the input file where the issue was found, if applicable, otherwise set to 0. Note that this number will be one less than the line number of your CSV file because of the header line.

Column
The column in the input file where this issue was found if applicable.
 

View Description View
Review the description of a pending assay in read-only format. To see the description in machine-readable format, click on the Export Files Pulldown and choose either the XML or ASN format (if you have data loaded, those options will also include the data in the file). If you want to edit the description, you must first delete any uploaded data, then go to the Edit Description View. If you want to remove the assay from the Deposition Gateway (no affect on PubChem), again make sure any uploaded data is deleted, then click the Delete Session Icon. For more information on specific assay description fields, see here.

Edit Description View
Make modifications to the description of a pending assay. This view is only available when any uploaded data has been deleted from your pending deposition. This view is never available for the Add/Change data action. Restrictions on what you can edit apply in particular for the Alter Description action, but in no case can you edit the External Assay RegID. For more information on specific assay description fields, see here.

History View
This view displays a detailed chronology of the processing steps for the pending assay action.  This history is only for the current pending action and does not include previous actions you have committed to PubChem for the same PubChem AID. To see an overall history of the actions you have committed to PubChem for all of your assays, click on the Deposited in PubChem tab. The columns are:
N
Count of processing step.

Originator
Who initiated the step, typically you, a curator or an automatic process ("Service Daemon").

Date
The date and time the step was taken.

Status
The name of the assay deposition step.

Comments
Additional description of the step taken.

View Data View
Display uploaded assay data in read-only format. Of course this view is only appropriate if you have uploaded an assay data file. If that file has passed the first phase of the Add Data step, which is "Data Parsing", then you will see your data file parsed into columns with the corresponding headers at the top and the data displayed on multiple pages as necessary.

The first column, "N", numbers the records and the next seven columns are the predefined columns specified earlier for the CSV format. The second column, SID, is the PubChem Substance identifier. Each SID number links back to the appropriate PubChem substance summary page. The remaining columns, TID1..N, correspond to the Results Definitions as shown in the View Description View. If you have failed "Data Validation", the second phase of the Add Data step, it is useful to look at this parsing and make sure it is what you intended. Perhaps you forgot a comma somewhere in your CSV file and your data is lined up with the wrong column headers.

Note that if your file could not get past the first phase of "Data Parsing", then an attempt will be made to show the text of your file as is. For convenience we will add line numbers, "N", and then show the text under the header "Unparsed Text".

If you would like to change something in your data file, first click on Delete Data, and then resubmit your modified file. If you would like to download your original CSV file or the machine-readable (XML/ASN) file generated from it, click on the Export Files Pulldown.

  • Commit Button
Export Files Pulldown
Clicking the Export Files Pulldown allows you to download various files. If you have submitted a CSV data file, you can download it or the parsed XML or ASN file that we create from it. You can also download the description only as an XML or ASN file.

Delete Data Icon
Clicking the Delete Data Icon enables you to delete the attached data file so that you can resubmit it or go backwards to edit your description or delete the action from the Deposition System. The Delete Data Icon is required for going backwards in the deposition process. Also, remember that deleting here refers to the Deposition system only; this action will have no affect on PubChem.

Delete Session Icon
Clicking the Delete Session Icon enables you to delete the current assay action from the Deposition System's pending list. This action will have no affect on assays in PubChem.

Commit Button
Clicking the Commit Button enables you to deposit the submission in PubChem. Your submission will be reviewed and, if approved, will be made public in the PubChem data system.

2.3.6  Assays > Deposited in PubChem Tab
This tab gives you a history of all assay actions taken by the Deposition Gateway which successfully affected PubChem. Each action will be listed on one line. This means that for one PubChem assay it will have a line for when the assay was first created. It could have additional lines for when it was modified, either by adding more data or by modifiying its description.

Clicking on a row will take you to the corresponding entry in PubChem.

The column headings can be used to sort the table. For example, clicking on the column "PC-Aid" will sort the table by that id. Clicking this column header a second time will reverse the order of the sort.

PC-AID
The permanent assay id number assigned to an assay in PubChem (not the temporary assay-id used in the Deposition Gateway).

Version
The version of your assay in PubChem upon completion of this action. This number will increase when you make significant changes to your description; please see the Replace assay tab for details.

Revision
The revision of your assay in PubChem upon completion of this action. In general this number will increase when you make small changes to your description; please see the Alter description tab for details.

Action
One of four types of actions you can perform on PubChem assays.
  1. New assay
  2. Add/Change data (Modify)
  3. Alter description (Modify)
  4. Replace assay (Modify)
Started
The date and time on which your assay operation began.

Finished
The date and time on which your assay operation entered PubChem.

User

2.4.2  Account Info > Contacts Tab
The Contacts Tab is only available for the primary user of a deposition account (i.e. the user who first opened the account for your data source).

List Contacts View
This view displays a summary of contact information for the "Primary Contact" (primary user) and below that one row for each of the "Additional Contacts". Clicking on the Primary Contact row takes you back to the Account tab. Clicking on a row of the Additional Contacts takes you to the View Contact view for that contact.

The contacts listed include information from the following columns:
  1. Full Name - Full name of the contact
  2. Email - E-mail address of the contact
  3. Title - Contact's title within the data source organization
  4. Phone - Phone number of the contact.
  5. Notify - Should this contact be sent deposition status e-mails.
Note that at the end of each Additional Contacts row is a "Delete" link. Use this very carefully as it will remove one of your organization's users from our system.

Add Contact View
This view allows you to add a contact for this deposition account. Please fill in all fields as completely as possible. You must fill in fields with a red "*".

Allow to login independently
The first checkbox on the "Add Contact" form determines whether this new contact will be able to login independent of the primary user.
  • Checked - "Username" and "Password" fields will appear. Ask the contact what username she would like; it must be unique within our system. For the password, either have the contact fill it in at your computer or set a temporary one and then the contact can change it. For more information on having multiple users on your account, click here.
  • Unchecked - The contact can receive update notifications on submissions as requested and his contact information is available for reference, but he must use the primary login/password to get access to the account.
After completing the contact information form, click on the "Register" button.

View Contact View
This View gives you read-only access to the contact's account information. Individual fields are defined just like the primary deposition account.

Edit Contact View
This View allows you to modify the contact's account information. Note that once a contact with independent login has been added, you should be very careful to make any changes to their account information. Each user can make his own changes. Also note that the primary user can change a contact's password, but can not view it. Individual fields are defined just like the primary deposition account. Please note: If you uncheck the Allow Login box for a contact that has an existing login, both his login and password will be lost.


2.4.3  Account Info > Preferences Tab
This tab displays a few preferences that you can review and revise. As with the other tabs, if you wish to make modifications, click on the "Edit Preferences" View on the left.

Data Source Description Terms
One of the more powerful aspects of PubChem and its background search engine, Entrez, is its categorization and linking of related data. This section offers a list of terms to categorize the type of data you provide to PubChem. Please choose at least one term (more than one is ok too). PubChem users looking only for toxicology data, for example, will be able to limit their search to those data sources, thereby making your data more accessible.
Auto-Confirm Substance FTP Depositions
This checkbox applies only to substance depositions made via FTP. If checked, all such depositions will be automatically confirmed on your end if they pass validation. This means you will not have to click on the "Commit" button on the user interface in such a case. The submission will still need to be reviewed and approved by a PubChem curator, but one manual step will be eliminated.

 3. PubChem Deposition Gateway FAQ's Top of Page

Q: I uploaded my file, now what?

A: The PubChem Deposition Gateway will parse and validate the data you submitted. You can watch this process proceed, or you may submit another file or logout and come back later. When this processing is complete, as denoted by the submission status bar or by receipt of an e-mail, you may want to review the submission. If you have a Test Account, and the submission proceeded without error, you have successfully tested your data and can be assured that your data is ready for use with the PubChem Deposition System. If you have a Deposition Account, and the submission proceeded without errors, you may commit your data to PubChem by pressing the "Commit" button.

Q: Can I supply an additional datasource URL as well as my datasource URL? Can I supply an additional substance URL as well as my substance URL?

A: You have two URL's per substance. One URL is associated with your data source name and the other is associated with your unique registry ID. Beyond that, you would need to use the Entrez "link-out" mechanism that can "piggy-back" URL's on your (or anyone's) substances.


Q: Can I supply multiple lines of additional searchable text per Substance?

A: All additional information should be put in the comments ("PUBCHEM_SUBSTANCE_COMMENT") section of the SD file. You can have as many lines as you need there. You could also put URL's there, too.


Q: If I have new information available, do I need to re-deposit the complete substance record including the new information or can I just deposit the new information?

A: You need to re-deposit the complete record, including the new information, using the same registry ID. This will "replace" the old data. [Actually, it will version the record and only the new version will be indexed, searchable, etc.]


Q: If a substance ceases to be part of my data, how do I delete the record in PubChem?

A: You will need to re-deposit the record such that it contains only the registry ID and a revoke tag ("PUBCHEM_REVOKE_SUBSTANCE"). We suggest that you provide a comment (a line of text) with this SD tag to designate why you revoked the record. For example, "Substance was removed 2005-05-21".


Q: If I find a mistake in my PubChem Substance record, is it better to update or remove my substance?

A: The best way is to "update" the substance record.


Q: After I get a deposition account, is my test account still active? Can I still use it to test submissions?

A: Yes, the test account is still active. You may continue to use that account for testing. Please be advised that test accounts will not allow you to deposit data into PubChem. Deposition accounts will allow you to deposit data into PubChem, after processing has successfully completed.

Q: We have various flags "nucleophile", "electrophile", "yuck" that we are starting to attach to molecules in our deposition. We'd like to send that data to PubChem in the most useful way possible. We think of them as "properties". What is the best way to do that?

A: The substance/compound properties you mentioned above will go to PubChem's "Comment". You can simply put them under sd tag <PUBCHEM_SUBSTANCE_COMMENT>.

Q: If we have CAS registry numbers, is it best to put them in <PUBCHEM_GENERIC_REGISTRY_NAME> or <PUBCHEM_SUBSTANCE_SYNONYM> ? Does it matter?

A: The PubChem original design let user to put all "Registry" items under <PUBCHEM_GENERIC_REGISTRY_NAME>. Since many depositors already put the CAS numbers under their own synonyms field, those CAS numbers will automatically go to the <PUBCHEM_SUBSTANCE_SYNONYM>. So it doesen't matter and up to you to put them in which field.

Q: We are starting to collect annotations of compounds e.g. inhibits enzyme XYZ with Ki=10uM using a spetrophotometric assay. Also, we annotate compounds as being aggregators (non specific inhibitors) at a particular concentration. This is starting to sound like something that overlaps with the PubChem Assay database. So far we don't have a lot of data to upload, but that may soon change. Can you advise us on the best way to send this data to you?

A: Yes. You are right. Such bio-data related to your substance will go to PubChem BioAssay database.

Q: From time to time, compounds become depleted at various suppliers. We would like to either A. indicate in the comment record that this supplier's stock is depleted. OR B. remove a supplier from the comment record completely.

A: Once you update your record, we will archive all old version content. We recommend you indicate in your comment.

Q: Is the only way to do this to upload the full SD record again, overwriting the previous one? I think this is true, but wanted to make sure.

A: Yes.

Q: Do you want compounds that are depleted in PubChem? I figure the answer is yes, because what you are really looking for is maximum coverage of chemical space. So I'm thinking, why don't you just run a combichem/de novo design program to enumerate millions of molecules, and then load them into PubChem? Obviously, just chemical space isn't what you're after. Can you help me understand the PubChem perspective on this issue?

A: PubChem substance database is depositors based. Every deposited substance will be assigned an SID. PubChem compound database is a non-redundant, structure unique database. Every compound in the database has a unique CID. If substance(s) linked with this compound become depleted, the compound will be deprecated/suppressed. We will keep all deprecated/suppressed compounds archived, and compounds will be never depleted.


 4. FTP Depositions & FAQ Top of Page

FTP-based deposition provides a path for completely automated data upload into PubChem. If you have a large amount of data to be uploaded into PubChem or if you update your data on a daily or weekly basis, you may be a good candidate to use the PubChem FTP deposition method.
To get started with FTP-based depositions, you must:
  • 1. Have an approved deposition account
  • 2. Have performed previous data uploads into PubChem
  • 3. Request an FTP account from PubChem
Please note that an FTP account is independent of your PubChem deposition account with different login credentials. The PubChem deposition account will be configured to interact directly with data uploaded via FTP. The procedure to create, setup, and configure your FTP account to interact with your PubChem deposition account will take one or more business days.


Substance-based FTP Depositions
To deposit data for a Substance deposition via FTP, you must:
  • 1. Upload a file using your FTP account
  • 2. Name the file you upload with the suffix ".sdf.in" (or ".sdf.gz.in", if a compressed file)
Please note that the file suffix lets the deposition system know your file is intended to be a new Substance deposition. After the file is recognized as being present, the file is transferred into the deposition system. There may be a delay between completion of your FTP upload transfer and before your uploaded file is processed, considering the deposition system processes FTP deposited data at particular times of the day and may wait to verify that your transfer is actually complete. FTP-based deposition processing begins when you notice the ".sdf.in" (or ".sdf.gz.in") suffixed file is removed from your FTP account directory and a status file is created. This status file has a suffix ".sdf.status". For example, if you upload the file "smid.sdf.gz.in", the status file created will be "smid.sdf.status".
The status file informs you of the processing progress. The possible status file contents and their meaning are listed below.

StatusMeaning
I Submitted
-P Parsing
!P Parsing Failed
P Parsed
-S Standardizing
!S Standardization Failed
S Standardized
-V0 Validating I
!V0 Validation I Failed
V0 Validated I
-V1 Validating II
!V1 Validation II Failed
V1 Validated II
C Committed for PubChem
A Approved for PubChem
R Rejected for PubChem
-D0 Uploading to PubChem
-D Depositing to PubChem
!D Depositing to PubChem Failed
D Deposited in PubChem

After processing completes to the point of "Validated II", you will need to log into the deposition system, review your submission, and then, if there are no issues, commit your data to be loaded into PubChem. An auto-commit feature can be requested, whereby the deposition commit step is performed on your behalf automatically. This removes the necessity for you to login and commit your data into PubChem. In many ways, FTP-based deposition is much like a normal deposited file. You can login to your deposition account at any time to see the progress of your deposition(s) or to get your SIDs. When processing is complete and your data is loaded into PubChem, you will see the suffixed file ".sdf.err" and, if all went well, the suffixed file ".sdf.out". The file with the ".sdf.out" suffix (e.g., "smid.sdf.out") is your report file containing your PubChem Substance identifiers (SID's).
Please note that the ".sdf.out" log file is a CSV text file, easily read by Excel or other spreadsheet applications. These files contain no column headers. The columns are in a following order:
  • Data Source Name
  • External Registry ID
  • SID
  • SID Version
  • Load Code
The "Load Code" column values, described below, allow you to know or track the substances that you have added, modified, or suppressed.

Load CodeDescription
0 substance load failed (internal error)
1 existing substance replaced (internal use only)
2 new substance created
3 new substance version, PubChem structure same
4 new substance version, PubChem structure changed
5 no change, identical substance
6 no change, but new PubChem structure (internal use only)
7 substance revoked/suppressed

The presence of a non-zero length file containing the suffix ".sdf.err" (e.g., "smid.sdf.err"), will indicate that there was a problem with your uploaded file and that your data may not be loaded into PubChem. The ".sdf.err" file will contain a human readable text message explaining why the FTP uploaded file failed. Please note that the status file is not deleted after processing and publishing are completed. The final contents, if all went well, will be "D", which will mean "Published".


FAQ

Q: How do I specify the URL associated with my data source name? Does PubChem use the URL I provided for my deposition account at registration time? Or, does PubChem use the URL specified using PUBCHEM_EXT_DATASOURCE_URL in the SDfile?
A: The URL specified when you created your deposition system account is used in the PubChem source page and is associated with your data source name in the PubChem sources display page, for example, the BioCyc data source name. The URL provided in the SD tag "PUBCHEM_EXT_DATASOURCE_URL" gives the data source URL per substance, which is allowed to change from substance to substance for the same data source name that you deposit.

Q: How do I deposit substance data using FTP?
A: You login to your private PubChem FTP account, upload your file(s), commit your processed data, and check back to the FTP account for your load report containing your SID's. Your uploaded substance deposition file must have the suffixed extension ".sdf.in" or ".sdf.gz.in", if "gzip" compressed. After the file is "recognized" by the PubChem deposition system, it will disappear from your FTP account and you will see a file with the suffix ".status". The status file will let you know at what processing stage your uploaded file is via a code in the ".sdf.status" file. After the processing is completed and your data is successfully loaded, there will be ".sdf.out" file containing your SID's.

Q: Is there any kind of report on the success or failure of the FTP uploaded substance data?
A: Yes, you can examine the ".sdf.status" file, the ".sdf.err" file, or the ".sdf.out" file. The ".sdf.status" file contains the current status of the data processing. The ".sdf.out" file contains a load report containing a list of records and the load action taken. The ".sdf.err" file may contain a human readable error as to why your FTP-based substance deposition failed.

Q: After we deposit our substances, will we get the SID's or CID's for linking purpose? How do we get the SID's or CID's? Will you put it on the ftp site for us to pick up?
A: After processing is completed and your substances are loaded into PubChem, a ".sdf.out" file will appear in your FTP account. This file will contain your SID's that correspond to your registry ID's. CID's are not provided.

Q: How do I compose a URL to link back to PubChem from my website?
A: To generate a URL to link to your substance, for example, SID 2244, the URL will be:
http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=2244

We do not recommend linking directly back to a CID associated with your substance using the "summary.cgi", as it may change as we change our preference for different tautomer or resonance forms of a structure. You may "safely" generate an URL to the CID associated with your substance via, for example, SID 2244:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?
cmd=PureSearch&db=pccompound&details_term=2244%5BSID%5D

Q: Is it possible to link back to PubChem without having to know the Substance identifier (SID)?
A: Yes, you can compose an URL using your data source name and external registry ID. For example, to make a like to the substance for the data source name "NIAID" and the external registry ID "115500", the URL would be:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?
cmd=PureSearch&db=pcsubstance&details_term=
niaid%5Bsourcename%5D%20AND%20115500%5Bsourceid%5D

Q: If we send records with the previous source ID again, will the previous record be overwritten?
A: Yes, the registry ID you provide is the key to the record. Whenever you send us a record with that registry ID, we will interpret it as an update, replacing the complete record with the information provided.

Assay-based FTP Depositions

Bioassay data depositions can be initiated via FTP in much the same way that substance depositions can, but for assays you must additionally specify the type of assay deposition operation.

To begin, follow the same three-step setup procedure as described for substance FTP depositions. Note that you use the same FTP account for depositing either substance or assay data.

Once your FTP account is setup, you should have the following directory structure under your top level directory:

You must decide which of the four types of assay operations you want to perform and place your file to be deposited into the appropriate directory highlighted above. You should be familiar with performing these assay deposition operations before trying them with FTP. For more information on them, see here.

Assay FTP Deposition File Format
To upload any kind of assay data or description changes, a single XML or ASN.1 file is required. This file must adhere to the specification for assays and be filled out as appropriate. Search in the specification file (XML Schema, ASN.1) for the tag PC-AssayContainer; this will always be the outermost container for your assay, whether it contains description and data or only description. You can find examples of such XML files from the PubChem public FTP site of bioassays. For assay deposition path-specific XML examples look at Bioassay XML examples for FTP section. No CSV files are permitted using FTP.
You can also download templates of XML files from pending depositions that you are making in the Deposition Gateway. You will need one file with both the data and description filled out in the cases of new, data_only or replace_all operations. For the alter_descr operation, only the description should be filled out. Let's now reiterate these instructions by assay deposition operation:

  • New assay deposition
    For this operation you need to fill out new description information including a unique aid-soure (RegId) and name for your assay, and assay data results. You can look at one of your existing assays from the PubChem FTP site for guidance.
    Your assay FTP upload file goes in the directory /assay/new. XML example is here.

  • Modify existing PubChem Assay
    For these three operations, you are doing something to affect your current assay in PubChem. Therefore, you need to specify the assay AID correctly so that it can be found. The best way to do this is to first copy the XML file of your current assay and modify it as you wish. In the following three types of Modify operations, we'll briefly mention what you should change.

    • Add/Change data without description change
      For this operation, you should take a copy of your current assay's XML file and replace the data section with the data that you want to add, delete or modify. Be careful to first remove all data or the system will think that you want to add that data again! Also note that for this operation you must make no changes to the existing description.
      Your assay FTP upload file goes in the directory /assay/modify/data_only. XML example is here.

    • Alter description
      For this operation, you should take a copy of your current assay's XML description file without the data section and make your minor alterations. Any significant changes, such as adding TID data result definitions, will result in an error.
      Your assay FTP upload file goes in the directory /assay/modify/alter_descr. XML example is here.

    • Replace assay
      For this operation, you should take a copy of your current assay's XML file and make your description and data section modifications. Please note that all of your existing data for this assay in PubChem will be replaced by the contents of this uploaded file.
      Your assay FTP upload file goes in the directory /assay/modify/replace_all. XML example is here.


XML Validation against PubChem XSD Schema
To increase the efficiency of the data exchange for your Bioassay FTP submission, PubChem highly recommends that depositors first validate XML files before uploading them to the PubChem FTP site for processing. XML validation will make sure that your file conforms to the PubChem Bioassay specification and should help speedup the deposition time by isolating XML errors. To check if your XML document conforms to the PubChem XSD Schema, the XML document must be validated against that XSD Schema. You can find PubChem's XSD schema here.

One XML validator that you might use is xmllint which is often included in standard Linux installations. To validate XML using xmllint one would run the following Linux command:

xmllint --noout --schema "ftp://ftp.ncbi.nlm.nih.gov/pubchem/specifications/pubchem.xsd" FileName.xml

Please be advised that PubChem does not support or maintain xmllint, but you can find more information on it here. Depositors may of course use any other equivalent XML package for validation.

Assay FTP Deposition Communication and Processing
As with substance FTP depositions, initial communication between you and our deposition system occurs through files in your FTP directory using a naming convention. Your input XML/ASN.1 file must end in ".in". Once that file is picked up by our system, it will try to process it and put the status of the deposition in another file with the extension ".status". There will also be a file ending in ".err" which will contain an explanation of any errors found. In some cases if a processing error occurs right at the start, the deposition will not have a status yet and the ".status" file will be empty.
The status file informs you of the processing progress. The possible status file contents and their meaning are listed below.

StatusMeaning
I Description created
U Data Submitted
-P Parsing Data
!P Data Parsing Failed
P Parsed
-V Validating
!V Data Validation Failed
V Data Validated
-T Depositing to Preview Database

T Deposited to Preview Database
C Committed for PubChem
A Approved for PubChem
R Revise for PubChem
-D Depositing to PubChem
!D Depositing to PubChem Failed
D Deposited in PubChem

After processing completes to the point of "Validated", you will need to log into the deposition system, review your submission, and then, if there are no issues, commit your data to be loaded into PubChem. An auto-commit feature can be requested, whereby the deposition commit step is performed on your behalf automatically. This removes the necessity for you to login and commit your data into PubChem. In many ways, FTP-based deposition is much like a normal deposited file. You can login to your deposition account at any time to see the progress of your deposition(s).
Once you have resolved any processing errors that might come up, your assay will proceed to the validated stage. At this point, you can switch to the Deposition Gateway web interface and view your deposition. This gives you more interactive information about your deposition and is necessary for you to confirm the validity of your new assay or changes to your existing assay. From the validated stage you will no longer need the FTP system.
