Good morning,

I'm trying to use a python script for ChimeraX version 1.5, to automate mutageneses on a specific protein.

As a first try, it looks like this :

from chimera
import runCommand
as rcrc("open " +
"hERGts_compiled.pdb")
rc("color red")
rc("surf");

So it refers to the chimera module for the runCommand. I tried to install it on Python through the command pip but it failed :

PS C:> python3 -m pip install chimera

Collecting chimera

note: This error originates from a subprocess, and is likely not a problem with pip.

So it looks like the temporary file generated has an error that doesn't allow the installation of the module, and so I cannot use any command from my script as runCommand is not recognized. There seem to be no mention of this issue in the mail archive but one colleague encountered the same problem, which I find strange. Do you have an idea on how to solve this issue ?

Thank you and have a great day,
