- check the .cif file to make sure it defines the ideal geometry that
you are expecting from your ligand to have;
- check .geo file to see if the restraints for that particular ligand
are actually used in refinement. The .geo file contains the list of all
the geometry restraints used in phenix.refine refinement (bonds, angles,
planarities, chiralities, dihedrals, non-bonded, NCS, custom defined
restraints and edits), for each and every atom, making it a complete
foot-print of geometry restraints used to obtain the final refined
- is your ligand located on a special position?
