Dear All,

If my protein contains a metal ion (Mg2+ for example, do I need a cif for the metal for phenix.refine? If my protein contains another ligand, which server can produce the ligand PDB suitable for the eLBOW? If my protein contains 2 ligands, then do I need 2 cif files for the phenix.refine or the phenix.real_space_refine?

I am looking forward to getting your reply.

Best regards.

Smith
