Subject: [AMBER] GAFF parameter
I would like to ask a question on NON Bond parameter of GAFF and on AMBER force field.
I have not a clear idea on how no bond vdw parameter work.
For example in the "gaff.dat" file at the bottom there are four column that begin with:
h1 1.3870 0.0157 Veenstra et al JCC,8,(1992),963
1) How is the right mening of these parameter?
2) Why the atomtype 'ho' has both zero parameters?
Thank you so much!
