[Chimera-users] Save marker sets from command line or python

Dear Chimera dev and community, I would like to save a marker set from the command line and ultimately do so in a script. Using the write command which I would use for PDB's, marker sets get saved in PDB format, of course. Is there a command to save the marker set as XML .cmm as it would from the volume tracer menu? I notice at the bottom of the following page this is a suggested development: https://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/volumepathtracer/v... - supply Python code for reading and writing the XML files containing saved marker sets Is it there already and I can't find perhaps? Thanks for your help as ever! Best wishes, Kyle
