Flow chart for the major phasing path encompassing native and derivative scaling, heavy-atom-based phasing, solvent flattening, negative-density truncation, and phase combination. Boxed entries represent programs while lines represent files. Optional paths for noncrystallographic symmetry averaging and phase extension are included by considering the additional programs offset from the main path by dashed lines.
