CCL: Tinker: harmonic torsion potential

 Sent to CCL by: "Gustavo A Mercier" [gamercier{=}yahoo.com]
 Hi!
 I am debugging a program. It would help if I could do some molecular mechanics
 with a force field that included a harmonic term for the torsions instead of the
 more common fourier series. TINKER (from Ponder's lab) has many options to
 modify the potential, including one for harmonic improper torsions. Is there a
 way of specifying a "proper" torsion harmonic term? I've gone over the
 manual and this does not seem to be an option.
 Thanks for your help!
