Dear All, Does anyone have a quick way to change the occupancies of atoms/residues rather than going through the Edit... Residue info... route? I can think of 2 common scenarios where this would be useful (to me at least!): 1. I want to change the occupancy of a ligand (e.g. to zero, so that it is ignored by refinement). As the ligand could be made up of several residues, a residue range function would be useful. 2. I have introduced an alternative conformation to a side-chain so that I now need to reduce the occupancy of a water molecule that clashes with this new conformation. Apologies if this is documented somewhere that I have neglected to look. Many thanks in advance, Dave Lawson ------------------------------- Dr. David M.
