Hi Harry
I use this link: https://mmcif.pdbj.org/converter/
to convert pdb to mmCIF . Hope, it was usuful for your modelled
coodinates.
Regards
Marta

Hi folks
I am in the situation of having coordinates of apoproteins (i.e.
polypeptide chains without prosthetic groups) in PDB format - but I
need them in mmCIF format so I can run them through a locally built
copy of AlphaFill.
I need something I can install locally, so web services are a no-no.
I've tried obabel and Coot to convert the PDB to mmCIF, but AlphaFill
doesn't like the files produced. Before I spend time searching through
available options on the interweb, does anyone know of a utility that
can provide me with suitable mmCIFs? Note that I *only* have the
coordinates because they come from modelling.
I'm assuming that I've run obabel and Coot correctly!
obabel:
alphafill process protein_obabel.cif filled.cif
Structure file does not seem to contain polymers, perhaps
pdbx_poly_seq_scheme is missing?
Coot:
alphafill process protein_A-coot-0.cif filled.cif
Error reading file 'protein_A-coot-0.cif'
parse error at line 2: This file does not seem to be an mmCIF file
