I want to to a potential energy scan of a dihedral (of a small organic molecule) by setting a dihedral angle, fixing those atoms involved, and doing a minimization. Then incrementing the angle and repeating. I can currently do all of this by using the gui (set torsion angle in build_structure,minimize with selected atoms fixed , then save and edit the final energies for each angle in reply log). I'm sure that this can be done with python. I am wondering if there is an available script to do this all.  As input I would have a set of torsion angles and as output I would like a table of angle and energy.
