# FigContact

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.

EXAMPLE

    FigContact 'selected' 'selected' 'bb' 'all' 3.0 5.0
