24 \&g_mdmat makes distance matrices consisting of the smallest distance
25 \&between residue pairs. With \-frames these distance matrices can be
26 \&stored as a function
27 \&of time, to be able to see differences in tertiary structure as a
28 \&funcion of time. If you choose your options unwise, this may generate
29 \&a large output file. Default only an averaged matrix over the whole
30 \&trajectory is output.
31 \&Also a count of the number of different atomic contacts between
32 \&residues over the whole trajectory can be made.
33 \&The output can be processed with xpm2ps to make a PostScript (tm) plot.
