Hi Prathvi, I don't know about startup using python, but you can start Chimera from the system command line with startup option --nogui and specify input files that could include a python script or Chimera command script for Chimera to execute. See the following help pages: Chimera startup: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/startup.html> System command-line Chimera startup options: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/options.html> I hope this helps, Elaine ----- Elaine C.

Hi,
Is it possible to use python to execute commands on the command line of UCSF chimera without actually opening its GUI on the Windows platform?
If not, then how to use python to open its GUI and execute the commands?
I tried the "subprocess.Popen()" and "os.system()" methods to run its GUI by passing the path of chimera executable (version 1.17.1) to them but chimera is displaying an error with exit code 1 (snapshot attached). However, I am able to launch chimeraX (version 1.6.1) via these methods.
