step 1 - get files from PDB:
phenix.fetch_pdb 1akg --mtz
step 2 - compute maps:
step 3 - convert map coefficients into map:
Note 1: you can request to output actual maps at step 2, so step 3 isn't
Note 2: all the above you can do in Phenix GUI.
Let me know if you still having problems with this and I will send
step-by-step instructions how to do this using the GUI.
