Hi everyone,

is there a way to select a residue by it’s array index, starting at 0 -> sequence length rather than using the residue id?

Hi Thomas, I think the answer is no, using only normal Chimera commands. However a simple Python script can do it, and such a script can be executed with the "runscript" command. I have attached a script that takes a model number and a residue index as arguments and selects the corresponding residue. If you put the script in your home directory then "runscript ~/selres.py 0 12" would select the 13th residue (input order) in model 0. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
