In the CCP4 program refmac5, you specify occupancy groups and then specify how to refine them.  The setup, afaik, is not automatic. Documentation for how to do it is here: http://www.ysbl.york.ac.uk/refmac/data/refmac_keywords.html#Occupancy You may also find this link helpful?

Well - I turn off occupancy refinement once there is a sort of consensus.. Disulphides often break after long exposures and you see the positive and negative blobs clearly. I must admit I usually just set 0.5 as occ , fix the surviving disulphide link and let the B values suggest a better ratio

Greetings everyone, I'm currently in the process of modeling a disulfide bond in two structures. However, when I attempt to model single occupancy for the cysteines involved in the bond, negative density blobs emerge within the disulfide bond. This suggests the possibility of alternate
