Gromacs does no such thing! What you're referring to is the *Gromos* force field, which is an entirely separate idea. There are all-atom force fields for use with Gromacs - OPLS, Amber, and even CHARMM, if you're adventurous :-) What you need to be concerned with is whether or not these QM charges and methodology are compatible with your force field of choice. > > 2. should i adjust that partial charges , If so how to do the same?
