[gmx-users] Add new residue to oplsaa force field

[fatemeh ramezani]

Dear JustinHydroxyprolin dihedral coefficients there are not in ffbonded file in oplsaa forcefield. I need to find it, and I add. 
I have Hydroxyprolin charmm parameters (dihedral parameters). How can I convert charmm dihedral parameters to oplsaa parameters?Can you help me so that I resolve this problem?Thanks for your guides
