You can try EDSTATS in CCP4 to get the numbers you want. This works very well for us.

Even so the ligand is non-peptidic, the program lists values for main- and side-chain. Is there a command which can be used to calculate a combined overall correlation coefficient? Thanks in advance for any advice, Andreas
