In this tutorial we will present you GROMACS Wizard Extension, a SAMSON extension for system preparation and simulation both locally and in the Cloud using the well-known GROMACS package.

The GROMACS Wizard Extension integrates the main GROMACS features into SAMSON – it provides the possibilities to easily prepare systems for simulation with GROMACS and run GROMACS simulations locally or in the Cloud, and get the results as simulation trajectories and plots. It is shipped with one of the latest versions of GROMACS (the latest version of the extension ships GROMACS 2021.3) which means that you do not need to compile and install the GROMACS package yourself. But it also gives you the possibility to use your local installation of GROMACS if you wish so.

This extension is available on Windows, Linux, and Mac.
