As a side note, we've been looking atthe effect of using a cutoff
(in proteins, AMBER7 with GB solvation). We find essentially no
correlation between relative energies of a set of structures without
cutoff and with cutoffs ranging anywhere from 8A to 20A
(using the same set of structures in each case). We are working on a
fix for this but the strongly suggest not using a cutoff with GB.
