## gmxdump

VERSION 4.5

### Description

gmxdump 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.

### Files

option | filename | type | description
--- | --- | --- | ---
`-s` | `topol.tpr` | Input, Opt. | Run input file: tpr tpb tpa
`-f` | `traj.xtc` | Input, Opt. | Trajectory: xtc trr trj gro g96 pdb cpt
`-e` | `ener.edr` | Input, Opt. | Energy file
`-cp` | `state.cpt` | Input, Opt. | Checkpoint file
`-p` | `topol.top` | Input, Opt. | Topology file
`-mtx` | `hessian.mtx` | Input, Opt. | Hessian matrix
`-om` | `grompp.mdp` | Output, Opt. | grompp input file with MD parameters

### Other options

option | type | default | description
--- | --- | --- | ---
`-[no]h` | gmx_bool | `no` | Print help info and quit
`-[no]version` | gmx_bool | `no` | Print version info and quit
`-nice` | int | `0` | Set the nicelevel
`-[no]nr` | gmx_bool | `yes` | Show index numbers in output (leaving them out makes comparison easier, but creates a useless topology)
`-[no]sys` | gmx_bool | `no` | List the atoms and bonded interactions for the whole system instead of for each molecule type
