The torsion angles in all amino acids in the PDB file will be tabulated.
Angles will be in degrees. A torsion angle of 999 degrees indicates that
this torsion angle does not exist (e.g. phi of the N-terminal residue),
or that there is something wrong with at least one of the atoms involved.
Torsion angles are calculated in degrees, using the IUPAC-IUB definitions
of torsion angles.
