[ccp4bb] DNA Restraints or Cif file for Phenix refinement

2013-03-19 Thread Yurong Wen
Dear All, Recently I generated a dataset of DNA protein complex. I built the DNA model with the simple mutate of nucleic acids, however when I tried to refine my structure, I came to the fatal error below with unknown bonded energy atom. (Similar to the phenix Tutorial 10: Generating ligand
