As an adjunct to B-factor vs occupancy thread, i might expect the b-factor to halve if the occupancy is set to 0.5 (but I'm only a molecular biologist....), if so how many cycles of refmac would it take for the value to settle? My limited experience is that it dosn't exactly halve but i do tend to use fewer cycles at later stages of refinement?
thanks Jim Brannigan
