All, I would like to parameterise the Dreiding force field for use with Gromacs. One thing I am not sure about is how to parameterise the dihedrals
The Dreiding paper has the form; E= 0.5k { 1 - cos[ n( phi - phi_o)]} However I cannot find this form in the Gromacs manual. The closest I can find in the Gromacs manual is: E = k [ 1 + cos(n*phi - phi_s) ] Does anyone know of a way to use the Dreiding form in Gromacs, or to convert to a form that is more suitable for use with Gromacs?
