To answer the Python side of this, chimera.Rotamers.getRotamers(residue) gets a list of rotamers (really Molecule instances) for that residue (Dunbrack library by default). Each of those Molecule instances has a 'rotamerProb' attribute, which is the value you see in the graphical user interface. You apply the rotamer you want by calling chimera.Rotamers.useRotamer(residue, rotamers) where rotamers is a list of rotamers to apply, probably just one (at a time) in your case because if you supply multiple rotamers then they will all be used by putting each one in a different alternate location. --Eric Eric Pettersen UCSF Computer Graphics Lab

Hi, I'm currently trying to write a python script which automatizes mutageneses on Chimera 1.16, and calculates clashes inducted by the change of amino acid through a local minimization (which explains why I'm using Chimera instead of ChimeraX). I would like to choose which rotamer to use depending on their probability from the rotamer library Dunbrack (for instance, when probability is >0.1), which is visible on the "Rotamers graphical user interface". Is there a way to extract these probability values using a script, in order to run it on a certain number of rotamers ? That way it would be quite automated. On Jul 1, 2015, Eric Pettersen advised to modify the "Python script that uses the functions in the Rotamers module" (here <https://www.cgl.ucsf.edu/pipermail/chimera-users/2015-July/011193.html>), but I don't which one it is.
