Hi Eric, Thank you very much!

You can run any regular Chimera command from Python by using the runCommand() function, e.g. to run "swapaa leu #0:248.a" you would: from chimera import runCommand runCommand("swapaa leu #0:248.a") You should look at this simple example of a Chimera Python script that does some looping and writes out result files: Very Basic Chimera Programming Primer<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.cgl.ucsf.edu_chimera...> --Eric Eric Pettersen UCSF Computer Graphics Lab On Aug 5, 2020, at 1:21 AM, mailman-bounces@cgl.ucsf.edu<mailto:mailman-bounces@cgl.ucsf.edu> wrote: Dear all, I am trying to simplify tedious and repetitive work through using Chimera. My work has to substitute a list of residue on a protein. For each row of the list, after the substitution, I need to save it as a separate file. Since I am a beginner of python coding, I would like to ask the following question before I attempt to code: -From what I said, is it possible to do it in Chimera? -Do I just call the Rotamer program out by using “useRotamers()”? If it is using that, how do I provide the residue number and residue type into the program? Thanks for your time and help.
