NAME
g_mdmat VERSION 3.3_beta_20050823
SYNOPSIS
g_mdmat -f traj.xtc -s topol.tpr -n index.ndx -mean dm.xpm -frames dmf.xpm -no num.xvg -[no]h -nice int -b time -e time -dt time -[no]xvgr -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 as a function of time, to be able to see differences in tertiary structure as a funcion of time. If you choose your options unwise, this may generate a large output file. 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.
