Harmonic Dihedral Trans State

Hi All,

I’m using the harmonic dihedral style (http://lammps.sandia.gov/doc/dihedral_harmonic.html).

In the paper that I’m referencing, they have d as -1 and state that trans is 0 deg. My question, since LAMMPS has trans at 180 deg, should d be set to -1 or 1?

Thanks
