ngmx

NAME

ngmx − displays a trajectory

SYNOPSIS

ngmx -f traj.xtc -s topol.tpr -n index.ndx -[no]h -nice int -b time -e time -dt time

DESCRIPTION

ngmx is the Gromacs trajectory viewer. This program reads a trajectory file, a run input file and an index file and plots a 3D structure of your molecule on your standard X Window screen. No need for a high end graphics workstation, it even works on Monochrome screens.

The following features have been implemented: 3D view, rotation, translation and scaling of your molecule(s), labels on atoms, animation of trajectories, hardcopy in PostScript format, user defined atom-filters runs on MIT-X (real X), open windows and motif, user friendly menus, option to remove periodicity, option to show computational box.

Some of the more common X command line options can be used:

-bg, -fg change colors, -font fontname, changes the font.

FILES

-f traj.xtc Input
Generic trajectory: xtc trr trj gro g96 pdb

-s topol.tpr Input
Generic run input: tpr tpb tpa xml

-n index.ndx Input, Opt.
Index file

OTHER OPTIONS

-[no]h no
Print help info and quit

-nice int 0
Set the nicelevel

-b time 0
First frame (ps) to read from trajectory

-e time 0
Last frame (ps) to read from trajectory

-dt time 0
Only use frame when t MOD dt = first time (ps)

− Balls option does not work

− Some times dumps core without a good reason
