.. class:: infomark

**What it does**

This tool performs a molecular dynamics simulation with GROMACS.

_____

.. class:: infomark

**Input**

       - GRO structure file.
       - Topology (TOP) file.

A variety of other options can also be specified:
       - MDP parameter file to take advantage of all GROMACS features. Otherwise, choose parameters through the Galaxy interface. See the `manual`_ for more information on the options.
       - Accepting and producing checkpoint (CPT) input/output files, which allows sequential MD simulations, e.g. when performing NVT and NPT equilibration followed by a production simulation.
       - Position restraint (ITP) file, useful for equilibrating solvent around a protein.
       - Choice of ensemble: NVT or NPT.
       - Whether to return trajectory (XTC or TRR) and/or structure (GRO or PDB) files.

.. _`manual`: http://manual.gromacs.org/documentation/2018/user-guide/mdp-options.html

.. class:: infomark

**Output**

       - Structure and/or trajectory files as specified in the input.
