[phenixbb] sa_omit map calculation

I want to calculate a sa-omit map around the same small region in the 3 molecules in the au. I have 2 questions: Can I include the 3 regions in the same omit box file? What does the following advice in the manual mean: (Note: be sure to use the weights in both resolve_composite_map.mtz and omit_region.mtz). I am not sure what weights we are talking about? Thanks for any help. Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220
