HIV Sequence Database

Programs and Tools
Search Interface retrieves HIV and SIV sequences, which can then be aligned and used to build trees Geography Search Interface retrieves HIV sequences based on geographical distribution Tools for working with sequences a complete list of our online tools, organized by function Alignments
HIV Premade Alignments includes Consensus and Ancestral Sequences, Subtype Reference Alignments (for use in trees, subtyping, and recombination analysis), and Complete Alignments (based on all sequences in the database) |

Sequence histograms
The output page of the HIV sequence Search Interface offers a new option, "Make Histogram". This option shows the distribution of your sequences across the HIV genome. At each position across the graph, the number of sequences overlapping that position is plotted as a bar. Colors within the bars represent different subtypes. The histogram allows you to see at a glance what regions and what subtypes are represented in your output.

Better names for downloaded sequences
The search interface now gives the option of customizing the names of downloaded sequences.
After clicking the "download sequences" button on the search results, click the "compose a label" link
and choose the database fields to make up the sequence labels. This makes it possible to save some or all of
the search information in the sequence names. 07 April 2009
TreeRate
We have released TreeRate, a web tool for re-rooting trees. Trees can be re-rooted using several methods including algorithms that optimize roots using single or multiple longitudinal samples. The intention of re-rooting the trees is to find the most homogeneous ("clocklike") evolutionary rate in the tree. Our previous tool Branchlength is now part of the TreeRate tool.

Special Interest Alignments
A new page provides HIV sequence alignments and accompanying data of special interest to research. Each set of data consists of one or more DNA sequence alignments, references, and any accompanying data that are available. Sets are selected for inclusion based on availability and the likelihood that researchers will have an interest in using the data in other studies. Your help is needed to suggest or provide additional sets of data for inclusion.

PepMap
New tool PepMap is available. The tool maps an input set of peptides
on the HXB2 reference sequence, generates a table with peptide
locations and peptide protein maps, similar to epitope maps.
