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 ----- Elaine C.

Dear Chimera users,
I obtained some dihedral angles around some rotatable bonds of my molecule's conformations. I used GA to get new sets of those torsions, now I need to convert them back to x,y,z coordinates (new conformations)
Is it possible to do that in Chimera? Please help.
Thank you. Chinh
