Is there any way I can fetch a pdb file from the web (e.g. $ open 1X2Y) and then also automatically fetch the associated cryoEM map if there is one? Looking in the mmCif file, there is a flag for the associated emdb-map (e.g. in 5ljo the mmCIF file there is a _pdbx_database_related.db_id flag with the corresponding id. It would be useful if this could be added as a flag to the open command if it isn't already. I'm sure it is also possible in some kind of script but I'm not hugely familiar with how to script in chimeraX.
