.. class:: infomark

**What it does**

This tool performs energy minimization of a system prior to a GROMACS simulation.

_____

.. class:: infomark

**Input**

       - GRO structure file.
       - Topology (TOP) file.
       - MDP parameter file (optional)

To take advantage of all GROMACS features, upload an MDP file with simulation parameters. Otherwise, choose parameters through the Galaxy interface. See the `manual`_ for more information on the options.

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

_____

        
.. class:: infomark

**Output**

       - GRO structure file.
