Refining a common occupancy (using one free variable) for a loop that is
in poor density is well worth trying. The loop may well have multiple
conformations and this may make it easier to find a second conformation in
the difference map. I also recommend refining the occupancies of any
I am looking for some advice.
(1) In shelex what should I mention to refine occupancy.
I have two molecule in asym unit.
In A molecule residues 89-92 is present, but in B these residues are
missing.
So I believe in B these residues should not be with zero occupancy, although
I donot find any
