Hi:

I’m refining a site where there’s two compounds, each at partial occupancy. I modeled that using alt codes and insertion codes combined, like this

ATOM   6500  CA ACYS B 101B

ATOM   6490  CA BXXX B 101A

How can I constrain the occupancies so that they sum to unity? I tried several option, but the distinct insertions seem to refine independently. Sorry if a similar question has been posted before, but I could not find a solution searching phenixbb.

Thanks!

Henry
