Maybe I'm missing something here, but don't you just import both cif files (for nucleic acid, and MPD individually) into phenix.refine? Did you try that?

Dear All:
I am using phenix-1.7.2 to refine my structure. Now i am facing a problem with .cif file. I could not generate  cif files for a modified nucleic acid and MPD at same time with phenix.elbow or phenix.ready_set. If I use phenix.elbow to generate cif file for modefied nucleic acid only, phenix .refine complains about MPD cif not found, same for MPD. If I combine two cif files together, phenix.refine also complains. Is there better to generate cif file containing both modified nucleic acid and MPD?
Many thanks for your help,
Xue
