The error message says that PDB file contains unknown/nonstandard residues or ligands. This needs to be addressed before proceeding to refinement. If you indeed have some unknowns in the model then you need to provide a proper CIF file with restraints, or resolve the conflict otherwise. Pavel On 9/18/17 17:57, Jiemin Zhao wrote:
Hi,
I got an error message when I try to refine a molecular replacement result. It says Fatal problems interpreting model file: Number of atoms with unknown nonbonding energy type symbols: 18 Please edit the model file to resolve the problems and/or supply a CIF file with matching restraint definitions, along with apply-cif-modification and apply-cif-link parameter definitions if necessary.
Could you help me with this problem?
Thanks!
