But then you would loose the info on the solvent mask parameters. These are 
only implicitly stored in FC_ALL. These values too are things to get from 
data.json.

Old program RSTATS would give r factor..

But easist to run 0 cycles of REFMAC - at least then you know what the scaling 
algorithm might be....

If you are using SFTOOLS you might as well use the CORREL function to calculate 
things.

Datamining is easier though. Every PDB-REDO entry has a data.json file that has 
all the numbers you need.
