[gmx-users] Tinker FF parameters vs. GROMACS

[Timothy E Pegg]

Hi, All.

I have a non-standard force-field defined in TINKER, but I'd like to use it in GROMACS. The TINKER documentation doesn't do a good job of describing how they define their torsion functions. Does anybody on this list know how TINKER's torsion potentials are defined and possibly how to convert the parameters into RB dihedrals for GROMACS?
