[phenixbb] .cif file created by Jligand for used in phenix.model_vs_data

The protein was covalently linked by my ligand and I used JLigand to generate the link record and the .cif file. This file can be used in Refmac successfully. But the .cif file cannot be recognized by phenix.model_vs_data nor phenix.refine. The program runs with the following message:
Sorry: Fatal problems interpreting model file:
Number of atoms with unknown nonbonded energy type symbols: 19
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
Any suggestions how to do this would be greatly appreciated.
Another question is, how can I generate a restraints file for COOT to do real space refinement? The .cif file is imported in COOT, but when I do real space refinement, the link bond still takes apart.
