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.
