Hi,

if you provide d_min it will define the radius of Ewald sphere for the purpose of structure factors calculation from the map. If you don't define d_min, it will do one of the two: try to guess it or compute all Fourier map coefficients in the box (don't remember which one of the two).

For phenix.map_to_structure_factors, it needs to input the resolution d_min. But for an EM map, usually the resolution is the general resolution of the whole map (or to some extent the average resolution of the whole map). Is d_min for  phenix.map_to_structure_factors the general EM map resolution, or the best resolution of the whole EM map, which is only for part of the EM map with the best quality?
