Pictorial description of how the plot to the
right was generated. A protein is represented by a circle. Assume that
there are two super-families, identified by the two different colours,
blue (solid) and black (pattern). For each protein in turn we computed
the distance to the closest protein with the same colour (and we used
it for the red plot) and the distance to the closest protein with a
different colour (and we used it for the green plot). In the figure,
the distances used for one of the blue proteins are shown.
