| ## GROMACS Flow chart Main Table of Contents | VERSION 4.0 Sun 18 Jan 2009

This is a flow chart of a typical GROMACS MD run of a protein in a box of water. A more detailed example is available in the Getting Started section. Several steps of energy minimization may be necessary, these consist of cycles: grompp -> mdrun.
