DESCRIPTION
     Create a Ramachandran plot with the first angle name
     on the x-axis and the second angle name on the y-axis.
     Only residues where both angles are selected are
     shown.

     The third argument is a space separated list of
     alternative residues (typically GLY).

     The fourth argument selects the background (allowed
     regions). The allowed regions were determined from
     378 different crystal structures with a resolution
     of 2.5 A or better. The regions where the density
     of points (PHI/PSI) from this statistic is highest
     are marked with color. The green regions contain 80%
     of all points, the green and yellow regions together
     95%, all colored regions together 98%. There is a
     background for all non-GLY/PRO residues, one for
     VAL/ILE/THR and one for GLY.

     The fifth argument selects the display style of
     residues not listed as alternative, the sixth
     argument the one for alternative residues.

     If the color option is selected, he colors of the
     markers is taken from the bond corresponding to the
     angle, otherwise they are all black.

     If the last option is selected and all angles shown
     in the plot have the same angle constraints, the
     allowed region is indicated in light grey.

     The user can select residues by clicking on symbols
     in the plot.
