# in the input mtz file, the map will take the unit cell dims
# of the later dataset.
# In 2, the Fcalc map is also calculated from the phase dataset
# mtz, however is forced to take the cell dims of dataset 1.
# In 3, the Fcalc and PHIC cols are instead generated from a
# pdb file, and so take the cell dims of that pdb file also.
# The important thing here is that the Fcalc map dimensions
# must match those of the atom-map at the same dose. If the PDB
# file is varied between datasets, then only methods 1 and 3
# will allow this. It may be wise to use method 3 as default
# since this does not depend on a separate mtz file for phases
