This script allows you to color two structures by distance displacement between an Open and Closed form of a protein, as calculated by PyMol's internal distance command. The pairwise distance is calculated between all-atoms. The distance displacement values are stored as B-factors of these residues, which are colored by a ''rainbow'' color spectrum, with blue specifying minimum  and red indicating maximum.

Introduction

This script allows you to color two structures by distance displacement between an Open and Closed form of a protein, as calculated by PyMol's internal distance command. The pairwise distance is calculated between all-atoms. The distance displacement values are stored as B-factors of these residues, which are colored by a rainbow color spectrum, with blue specifying minimum and red indicating maximum.

Do keep in mind, all original B-factors values are overwritten!

There exist one version.
ColorByDisplacementAll is between All atoms in residues and is quite slow => 3-5 mins for a run. Ideal for sticks representation.

You have to specify which residues should be used in the alignment procedure, or it will take all residues as standard

V.2 is implemented the 2011.01.06 - Due to a bug in coloring.

Bug in code

A bug in the boolean operator of the spectrum command has been found. This versions work for version 1.3 Educational product.
For other versions of pymol, try to change (comment/uncomment) the cmd.spectrum line. The other spectrum line works for Open-Source PyMOL 1.2r3pre, Incentive product

Examples

ColorByDisplacementAll O5NT, C5NT, super1=resi 26-355, super2=resi 26-355, doColor=t, doAlign=t

ColorByDisplacementAll O5NT, C5NT, super1=resi 26-355, super2=resi 26-355, doColor=t, doAlign=t, AlignedWhite='no'

Dark blue is low displacement, higher displacements are in orange/yellow/red.
Residues used for alignment is colored white. Can be turned off in top of algorithm. Residues not in both pdb files is colored black
