I performed a 100 ns MD of a protein in an organic solvent and I want to calculate the change in torsion angles of a specific residue side chain over the simulation. is there any script to do that ?
You could use the following two links to help you out using python to calculate the torsion angle.

I want to create a coarse grained model of a protein solvated in ethanol box. I could do that with water by using charm-GUI and VMD but with non standard solvent it seems complicated. any suggestions?
