View a trajectory on an X-Windows terminal

## NAME

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

## SYNOPSIS

```
gmx view [-f [<.xtc/.trr/...>]] [-s [<.tpr>]] [-n [<.ndx>]] [-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 files:*

- **-f \[\<.xtc/.trr/...\>\] (traj.xtc)**

  *Trajectory: xtc trr cpt gro g96 pdb tng*

- **-s \[\<.tpr\>\] (topol.tpr)**

  *Portable xdr run input file*

- **-n \[\<.ndx\>\] (index.ndx) (Optional)**

  *Index file*

*Other options:*

- **-b \<time\> (0)**

  *Time of first frame to read from trajectory (default unit ps)*

- **-e \<time\> (0)**

  *Time of last frame to read from trajectory (default unit ps)*

- **-dt \<time\> (0)**

  *Only use frame when t MOD dt = first time (default unit ps)*

## KNOWN ISSUES

- •

  *Balls option does not work*

- •

  *Some times dumps core without a good reason*
