Hi all,
I was wondering if someone out there who is experienced with model compound
parametrization, could tell me how should one define the system+water
gaussian calculations for the charmm FF charges determination. Is it one per
one molecule? I can't figure it out. Besides, does someone knows of an
extended user guide to paratool?
thanks in advance,
Jose
