Sorry for making you confused. I don't have much experience in MD.I want to
use exact parameters from literature and trying to add these parameters in
the frcmod file.For dihedral angle, in literature they mentioned three
barrier height (Vn) values .These parameters are made for OPLS-AA
framework.Out of these three barrier height values which one I wilI choose
for mention in frcmod?.
