[lammps-users] Improper coefficient in AMBER force field

Dear Dr. Andrew Jewett,

I hope that you are doing well. I have a little problem with the AMBER force field and I hope that you help me. In moltemplate you listed Improper Coefficients for AMBER force field, while there is no sign of this in the original paper (doi: 10.1002/jcc.20035). Where did you find them?

Thank you
