Hi Joshua,
ChimeraX gets the chain descriptions from a PDB file by processing the COMPND records, specifically the MOL_ID, MOLECULE, CHAIN, and SYNONYM "sub-records" of the COMPND records, as per the somewhat ugly code at lines 1482-1525 of atomic/src/structure.py.  
For mmCIF files, it does analogous things by processing the struct_asym and entity tables.

Hello,

When I load a pdb into chimerax, a table appears with the chain IDs and associated descriptions. I would like to change the chain descriptions. How do I do that?

Thank you,

J
