Hi all. How to add a difference map peak value to B-factor column in Phenix-Coot after isomorphous difference map? Because what I get (after Phenix Isomorphous Difference Map) is a pdb with the peaks (chain A) and holes (chain B) with their positions given by UNKnown atoms, 1 for occupancy and in the B-column their peak-or-hole value. I would be happy if I could get the actual atoms with positions and the peak-or-hole value in the B-column. Thanks again and again.
