chi_angles_atoms
The name of the atomic group that determines the side chain torsion angle in amino acids. Each amino acid has a maximum of four side chain torsion angles, among which ALA and GLY have no side chain torsion angle. Each torsion angle is determined by the position of 4 atomic groups (Dihedral Angle).
