1) Convert the CNS protein alone reflection file to an mtz file with
FreeR flags labelled
2) Convert ligand data to myz file - easiest to use the IMPORT scaled
data tool in Data Processing module if you have a *.sca file.
Say you want to import FreeR flag from another mtz file (the
protein-alone one)
Then you will get the protein-alone FreeR flags plus an extended set for
the new data
Then convert the new ligand mytz back to CNS format
