[Chimera-users] Coloring range for residues

[Eric Pettersen]

Hi Ibrahim,
	I'm not 100% sure why you want to rainbow the highlighted part of  
your structure, rather than use a single color, or color the rest of  
the structure dark gray, or make the rest of the structure semi- 
transparent, or many other possible highlighting schemes.
	Anyway, there's no way to do it without resorting to (simple)  
Python.  Put the following in a file that ends in ".py":

import chimera
residues = chimera.selection.currentResidues()
residues.sort()
for i, r in enumerate(residues):
	r.highlightNum = i+1

	Then select the residues you want highlighted in Chimera.  Run the  
Python script by opening it with the "open" command or with the File- 
 >Open dialog.  Then run this Chimera command:

	rangecolor highlightNum,r min blue mid white max red sel
