[Chimera-users] torsion angles to x,y,z coordinate

Hi Chinh,
You can change torsion angles using the Adjust Torsions GUI (in menu under Tools... Structure Editing)

... or the rotation command

If you have lots of values, you would probably want to script it, but it probably wouldn't be that easy/convenient since the commands (or python, if you do a python script) will need to specify the 4 atoms used to define each torsion.

I hope this helps,
