# g\_view(1)

View a trajectory on an X-Windows terminal

Part of [gmx-view(1)](/gmx-view/1.md).

## NAME

gmx-view - View a trajectory on an X-Windows terminal

## SYNOPSIS

gmx view \[-f \[\<.xtc/.trr/...\>\]\] \[-s \[\<.tpr/.tpb/...\>\]\] \[-n \[\<.ndx\>\]\]\
          \[-nice \<int\>\] \[-b \<time\>\] \[-e \<time\>\] \[-dt \<time\>\]

## DESCRIPTION

**gmx view** 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.

## OPTIONS

Options to specify input and output files:

**-f** *\[\<.xtc/.trr/...\>\] (traj.xtc) (Input)*\
     Trajectory: xtc trr cpt trj gro g96 pdb tng

**-s** *\[\<.tpr/.tpb/...\>\] (topol.tpr) (Input)*\
     Run input file: tpr tpb tpa

**-n** *\[\<.ndx\>\] (index.ndx) (Input, Optional)*\
     Index file

Other options:

**-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)

## KNOWN ISSUES

\- Balls option does not work

\- Some times dumps core without a good reason
