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