Dear All,
I have looked everywhere for answers on this one with no luck... I have several structures at reasonable resolution 1.7 to 1.1A. I have performed unrestrained refinement on the model which is fine for the core protein and ligands but the surface atoms start flying off a bit. So what I would like to do is unrestrained refinement only on the ligands and leave the protein restraints in place. I have a feeling that if I cannot do it in Refmac I can in phenix but I cannot find anything out about that either. All help greatly appreciated, yours, Matt.
