In the meantime if you have ccp4 installed, sfall will calculate the
structure factors, which you could display as above or with ccp4.

You'll have to give unit cell as well as space group, and it
won't add bulk solvent which may not be a problem for your use.

something like:
  (or unit cell and SG can be on CRYST1 card in model.pdb)

sfall  XYZIN model.pdb  HKLOUT model.mtz << END-sfall
CELL 15 20 25 90 90 90
SYMM P212121
RESO 30 2.1
