I want to create a topology file for ammonia molecule and run using oplsaa
FF. since ammonia molecule is not there in oplsaa FF, i created the
molecule in Avogadro software and saved it as .pdb format. Then using the
topolgen_1.1.pl pearl script (script by Justin Lemkul), i generated the
topology. But the net charge on the molecule is 0.18 (for one molecule of
1] So how do i neutralize the net charge (because it is difficult to add a
non-integer charge), and hence carry out the simulation as neutral
2] Or is it possible to run by other scripts like mktop, acpype etc..??
Any suggestions are appreciated.
