, 0,5 and so on.. But in fact B factors and occupancies are highly correlated, and you would probably expect a ligand soaking in after crystallisation to have higher B factors, so it is very difficult to get a definitive answer. Eleanor nkamiya wrote: Dear all, This is my first mail to

[ccp4bb] Occupancy refinement of substrate using refmac5

2007-12-17 Thread nkamiya
Dear all, This is my first mail to CCP4BB. I'm now refining crystal structures of an enzyme at a resolution of 1.5A using refmac5 through CCP4i. Before X-ray data collections, the substrate and co-factor ions were soaked into the crystals. Their occupancies seem to be less than the unity because
