[gmx-users] proper dihedral function!!!

[nanyu101]

Dear gmx-users,
  

    I have a question about dihedral functions.
  Firstly, do Gromos 96 43a2 force field in Gromacs has three dihedral types.If so,what's the functions of these types?In ffG43a2bond.itp file, I just found only one force constant. If I hope to use more than one force constant,how can I fix it?

Thanks for your comments.

Best wishes,
Xianhui Wu
