Dear all, I'm currently working on a structure with a series of ligands which have occupancies of ~80% (according to phenix.refine). So far so good, a few of these also show alternate conformations which I'd like to let phenix refine as well, but phenix.refine adjusts the occupancy of the whole ligand (conformation A+B) automatically to 1. I see that this is useful in most cases, but not in this one. Is there a possibility to adjust the overall occupancy or another work-around that anyone can suggest?
