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

Onderwerp: [ccp4bb] calculation of map correlation coefficient

Hi,

I tried to use the program map correlation to calculate the 
correlation between a small molecule ligand and the corresponding 
electron density on a per residue basis. 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
