Molecules To Go Request FORM - IMAGES
Through the Molecules To Go Request FORM one may request a PDB data file
to be returned as a "GIF" format image in one of several different drawing and color
styles and according to user specified X,Y,Z rotation parameters.
The Image buttons specify the generation of a GIF image
of the designated structure in the appropriate drawing style.
(line drawing, ball and stick, space filling, ribbon)
The returned GIF image is displayed by the Web client
or its associated image viewer.
Ribbon images generated by Rasmol depict ligands in space filling
mode when present.
Molecules To Go now offers two alternate methods of generating images:
- Rasmol offers the advantage of faster image generation and a greater
number of color options
- Images produced by Raster 3D take longer
to generate but tend to be of a superior image quality.
Image generation by Raster 3D averages approximately 30 seconds.
Due to their complexity or unusually large
size some PDB structures cannot be imaged by this utility and in such circumstances a blank GIF images
is usually returned.
The image generated is based on the user specified X,Y,Z
coordinates.
There are also a number of different coloring schemes to choose
from:
These color schemes have the following characteristics:
- Atom Type -- (CPK) "atoms" colored according to their element type
- Chain -- each chain within the structure is colored differently
- Structure * -- Protein molecules color coded based on their
secondary structure characteristics: Red=helix; Yellow=beta-sheet;
Blue=turn; White=all others.
- Residue -- each residue is colored with a unique color for each amino acid
type.
- Group * -- residues are colored based on their position in the macromolecular
chain... colors are graded from N to C terminus.
- Temperature * -- colour codes each atom according to the anisotropic
temperature (beta) value stored in the PDB file.
*These color schemes only available for images created by the
program Rasmol
