Cc: Greg Couch added

Using the PDB format version, chain C correctly contains only the A-V-L residues and the others are treated as non-polymeric entities covalently bound to the peptide chain (and therefore addh works correctly) despite all the residues being in the SEQRES records (or equivalent). Will need to investigate how to make the mmCIF processing smarter in this regard.

Resolution: fixed
Status: acceptedclosed

Not really sure if the mmCIF or PDB treatment is better (lean to PDB), but I've changed AddH to not try to "complete" a C-terminus that doesn't look like a carboxylate: https://github.com/RBVI/ChimeraX/commit/26956fbda6f937df3dc233daab57eeaa76d834c0

Committed to develop and 1.6 release branches.
