Hi Georg,

what you get doesn't look good.

I think you can answers and fix suggestions to this here

" 13 typical occupancy refinement scenarios and available options in 
phenix.refine"
https://www.phenix-online.org/newsletter/CCN_2015_07.pdf

Make sue input occupancies within the residue name&number are the same.
