You can script most of it with Chimera commands:<br>
<br>
activate torsion (do that part just once), increment torsion with “rotation”:<br>

<br>
select atoms to be frozen (or not) in minimization with “select":<br>

<br>
“minimize” command:<br>

That would still entail saving the Reply Log and editing it yourself. For saving log contents, these previous posts may be useful:<br>

I hope this helps,<br>

> 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.<br>
