# gmxdump\_d(1)

Make binary files human readable

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

## NAME

gmx-dump - Make binary files human readable

## SYNOPSIS

gmx dump \[-s \[\<.tpr/.tpb/...\>\]\] \[-f \[\<.xtc/.trr/...\>\]\] \[-e \[\<.edr\>\]\]\
          \[-cp \[\<.cpt\>\]\] \[-p \[\<.top\>\]\] \[-mtx \[\<.mtx\>\]\] \[-om \[\<.mdp\>\]\]\
          \[-nice \<int\>\] \[-\[no\]nr\] \[-\[no\]sys\]

## DESCRIPTION

**gmx dump** reads a run input file (**.tpa**/**.tpr**/**.tpb**), a trajectory (**.trj**/**.trr**/**.xtc**), an energy file (**.ene**/**.edr**), or a checkpoint file (**.cpt**) and prints that to standard output in a readable format. This program is essential for checking your run input file in case of problems.

The program can also preprocess a topology to help finding problems. Note that currently setting **GMXLIB** is the only way to customize directories used for searching include files.

## OPTIONS

Options to specify input and output files:

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

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

**-e** *\[\<.edr\>\] (ener.edr) (Input, Optional)*\
     Energy file

**-cp** *\[\<.cpt\>\] (state.cpt) (Input, Optional)*\
     Checkpoint file

**-p** *\[\<.top\>\] (topol.top) (Input, Optional)*\
     Topology file

**-mtx** *\[\<.mtx\>\] (hessian.mtx) (Input, Optional)*\
     Hessian matrix

**-om** *\[\<.mdp\>\] (grompp.mdp) (Output, Optional)*\
     grompp input file with MD parameters

Other options:

**-nice** *\<int\> (0)*\
     Set the nicelevel

**-\[no\]nr**  *(yes)*\
     Show index numbers in output (leaving them out makes comparison easier, but creates a useless topology)

**-\[no\]sys**  *(no)*\
     List the atoms and bonded interactions for the whole system instead of for each molecule type

## KNOWN ISSUES

\- Position restraint output from -sys -s is broken
