[Chimera-users] Coloring range for residues

Dear Chimera team, I wonder if there is a way to color a certain range of residues using rainbow. I tried to use the rainbow command with atom_spec but it applied for the whole chain. What I want to do is to color part of the structure as a rainbow (from blue-white-red) with an increasing order of residues number. I just wanted to highlight a region of conformational change so the eye can follow which part of the structure has changed dramatically. Thanks in advance for your help. Ibrahim -- Ibrahim M.
