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

[Elaine Meng]

Hi Chinh,
You can change torsion angles using the Adjust Torsions GUI (in menu under Tools... Structure Editing)
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html#adjust>

... or the rotation command
<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/rotation.html>

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,
Elaine
