NAME
     gmx-dump - Make binary files human readable

SYNOPSIS
	gmx dump [-s <.tpr>] [-f <.xtc/.trr/...>] [-e <.edr>] [-cp <.cpt>]
		 [-p <.top>] [-mtx <.mtx>] [-om <.mdp>] [-[no]nr]
		 [-[no]param] [-[no]sys] [-[no]orgir]

DESCRIPTION
     gmx  dump	reads  a run input file (.tpr), a trajectory (.trr/.xtc/tng), an
     energy file (.edr), a checkpoint file (.cpt) or topology  file  (.top)  and
     prints  that  to standard output in a readable format.  This program is es-
     sential for checking your run input file in case of problems.

OPTIONS
     Options to specify input files:

     -s <.tpr> (Optional)
	    Run input file to dump

     -f <.xtc/.trr/...> (Optional)
	    Trajectory file to dump: xtc trr cpt gro g96 pdb tng h5md

     -e <.edr> (Optional)
	    Energy file to dump

     -cp <.cpt> (Optional)
	    Checkpoint file to dump

     -p <.top> (Optional)
	    Topology file to dump

     -mtx <.mtx> (Optional)
	    Hessian matrix to dump

     Options to specify output files:

     -om <.mdp> (Optional)
	    grompp input file from run input file

     Other options:

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

     -[no]param (no)
	    Show parameters for each bonded interaction (for comparing dumps, it
	    is useful to combine this with -nonr)

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

     -[no]orgir (no)
	    Show  input  parameters from tpr as they were written by the version
	    that produced the file, instead of how  the  current  version  reads
	    them

KNOWN ISSUES
     * The .mdp file produced by -om can not be read by grompp.
