Angle reports the bond angle for three specified atoms or the dihedral angle for four specified atoms. The order of specification is important, but atoms need not be connected. The angle value in degrees is reported in the status line and Reply Log.
The atoms can be specified collectively using the word selected, sel, or picked if the current selection contains only the three or four atoms of interest; the order in which the atoms were selected (most likely picked) is used. When order information is lacking (for example, the atoms were selected simultaneously), the angle actually measured may not be the one intended.
The angle command provides a static measurement; changes are not reported automatically. To monitor an angle continuously, use the Angles/Torsions panel instead.
