NAME
     FigContact - show contact map

SYNOPSIS
     FigContact name name name name expr expr

DESCRIPTION
     Create a figure showing a contact map of residues. The
     first argument gives a property name, the residues
     with this property set will be shown on the horizontal
     axis. The residues with the property given as second
     argument will be shown on the vertical axis.

     For each of these residues, only the atoms with the
     property given as third argument will be considered
     for the contacts shown on the top-left side of the
     diagonal, the ones with the property given as fourth
     argument will be considered for the bottom-right side
     of the diagonal.

     Two distances are given as fifth and sixth argument.
     Nothing will be drawn if the smallest distance between
     two atoms of the corresponding residues is larger than
     the maximal distance. A black square will be drawn if
     it is smaller than the minimal distance. Values in
     between are shown with increasing levels of grey.

     If more than one molecule is selected, they all need
     to have the same structure. The distance of each atom
     pair is calculated as average over the distances in
     each individual molecule. So what is used for the plot
     is the minimal average distance of atom pairs between
     the corresponding residues.

     This command supports groups.
