[PyMOL] How to get all side-chain torsion angles of a protein structure

[Cavi <cav...@ya...>]

Hi all,
I would like to get all the dihedral angles of a protein structure. I'm most especially interested in the side-chain angles. I've only been able to get the phi and psi angles using PyMOL, which is not exactly what I need. Does anyone have a script to calculate the side-chain dihedral angles?
Thanks in advance!
Cheers,Cavi
