Hi, I am trying to deposit cif files from phenix.refine using the last stable version and the release candidate. In both, I seem many instances of C00089 covale NAG D 2012 O4 NAG AM . O4 . BMA D 2013 C1 BMA AN . C1 . 'Custom glycosidic links need to be generated when the atom names of the carbohydrates don't conform to the standard.' for every glycan-glycan bond, but 'Taken from Monomer Library or GeoStd' for ASN-NAG, which does not make sense. The log file says the ALPHA1-3, ALPHA1-6, BETA1-4 and NAG-ASN links were properly applied, but the cif only mentions NAG-ASN. The cif also includes a link definition only for NAG-ASN, but none of the other glycosidic bonds. The structures appear to have proper geometry for glycosidic bonds, so this is probably just a cif-only issue. Also, is there a way to output the cif where every glycan residue does not get a new chain (this one goes up to chain AV=48 chains)? I found at least one phenix-refined case in the PDB where one glycan chain gets a single chain ID. Admittedly, that might have been fixed post phenix.refine.
