NAME

       g_mdmat - calculates residue contact maps

       VERSION 4.5.4-dev-20110404-bc5695c

SYNOPSIS

       g_mdmat	-f  traj.xtc  -s topol.tpr -n index.ndx -mean dm.xpm -frames dmf.xpm -no num.xvg -[no]h -[no]version -nice int -b time -e time -dt
       time -xvg enum -t real -nlevels int

DESCRIPTION

	g_mdmat makes distance matrices consisting of the smallest distance between residue pairs. With  -frames, these distance matrices  can	be
       stored  in  order  to see differences in tertiary structure as a function of time. If you choose your options unwisely, this may generate a
       large output file. By default, only an averaged matrix over the whole trajectory is output.  Also a count of the number of different atomic
       contacts between residues over the whole trajectory can be made.  The output can be processed with  xpm2ps to make a PostScript (tm) plot.
