Thu,

A ChimeraX equivalent would be

from chimerax.atomic import AtomicStructure structure_list = session.models.list(type=AtomicStructure)

The chains are in a structure's "chains" attribute.

Best,

[EXTERNAL SENDER - PROCEED CAUTIOUSLY]

Good morning, I am editing a python script that previously used the command chimera.openModels.list(modelTypes=[chimera.Molecule])to return a list of open molecules. Do we have a similar command in ChimeraX or is there any other way to get a list of protein chains in ChimeraX? Thank you very much.

Best regards, Thu
