Hey, I've been doing a lot of work with PDB assemblies, which are distributed as multi-state structures. I would like to be able to align them based on individual chains from individual states. However, I haven't been able to figure out any way to uniquely identify atoms by state.
The select statement contains a `state` parameter, but as noted in this 2010 thread <https://www.mail-archive.com/pymol-users@lists.sourceforge.net/msg08224.html> it doesn't seem to do anything. The thread also suggests using cmd.get_model(), but I'm not sure how to get a selection based on a chempy.models.Indexed instance. My current workaround is to split_states, use alter to make all the chains unique, then merge the structures again. This is incredibly tedious. Does anyone know a better way? It would be nice if (1) the select command were fixed, and/or (2) add a property selector for states. Cheers, Spencer
