Dear ChimeraX community and developer,

I am trying to deposit my map with model.

I save the model from pdb to cif in ChimeraX because of large amount of atoms, then got error as "Missing '_entity_poly.pdbx_strand_id' item. 

I tired to use pymol to open my pdb and save it as cif by 'Export Molecule', in which I just use the default options.

I checked the saved cif in ChimeraX, which is weird since it couldn't be show in cartoon style.

Is there any easy to handle this in ChimeraX or any option should be used in the 'Export Molecule' in Pymol?

Thanks and cheers,

Yanhe
