Description

Here is a small script to color proteins according to residue type. Call it from your .pymolrc or from within pymol: "run resicolor.py". Then, issuing "resicolor" will apply the scheme. Selections are supported: "resicolor chain A" will apply the scheme only to chain A. This functionality is also available as a plugin (Resicolor_plugin).
