+All selected angles are set to the given '''value''', given in degrees.
-selection ''string''. By default, the selection made in the most recent
-'''angles select''' command is used, or all angles if no selection has
-been made so far.
-The value of a torsion angle can be set with the parameter '''value'''. The
-''string'' is a real number or a real expression that may contain the
-symbol '''value''' to represent the current value of the torsion angle.
-Torsion angle values are given in degrees.
-Torsion angles are fixed to their current value if the option '''fixed'''
-is given. Fixed torsion angles are non-rotatable and cannot be changed
-during minimization or torsion angle dynamics.
-Torsion angles are made rotatable if the option '''free''' is given. Free
-torsion angles can be changed during minimization or torsion angle
-dynamics.
-Initially, all torsion angles defined in the library are rotatable
-except for those called OMEGA, which are typically used for the
-peptide bonds in polypeptides. OMEGA angles are fixed to 180 degrees
-(trans). Optionally, the OMEGA angle preceding a given amino acid
-residue can be fixed to 0 degrees (cis) by a preceding the residue
-name in the sequence (.seq) file by a lowercase '''c'''.
