[ccp4bb] Calculation of Selection Volumes

[Buz Barstow]

Dear All,

I'd like to find a way to calculate the volume of an arbitrary  
selection of atoms in a protein structure. Could anyone suggest a  
program that could perform this task, ideally, one that could be  
called from inside pymol and calculate the volume of a pymol selection?

Thanks! and all the best,
