| 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'''.
