Simplify Molecular Simulations with Your Custom GROMACS Version

If you are a molecular modeler working with GROMACS, you might already be familiar with some of the challenges around ensuring reproducibility, integrating toolchains, or using hardware-specific optimizations. Did you know that GROMACS Wizard, part of the SAMSON platform, allows you to seamlessly integrate your own custom version of GROMACS?

Why Use a Custom GROMACS Version?

Although GROMACS Wizard comes pre-packaged with one of the latest GROMACS versions, there are compelling reasons why you might want to use a custom GROMACS version:

  • Reproducibility: Ensuring compatibility with previously published simulations requires specific versions.
  • System-specific optimization: If you have optimized a GROMACS build for your hardware, integrating with that version can boost performance.

Setting Up Your Custom GROMACS Version

Configuring GROMACS Wizard to use your local GROMACS version is straightforward. Begin by opening the Settings in the GROMACS Wizard. Open settings

Once in the settings menu, follow these simple steps:

  1. Enable the Use a Different GROMACS Version Option: Check the corresponding box to switch from the pre-shipped version.
  2. Specify Your GROMACS Executable Path: Select the GROMACS executable on your system (gmx.exe on Windows or gmx on Linux/macOS) using the browsing button. If GROMACS Wizard recognizes your executable, it will display its version.
  3. Provide the Path to the Force Fields Folder: Locate the folder containing forcefield.ff directories. Typically, this is $HOME/gromacs/share/top/ on Linux/macOS installations. Custom GROMACS path

After completing the above, GROMACS Wizard will seamlessly integrate your custom version, giving you full control over locally performed simulations.

Integrating Flexibility into Your Workflow

By allowing custom GROMACS integration, GROMACS Wizard eliminates barriers around rigid pre-installed package versions. Whether you’re aligning simulations with specific legacy data or optimizing for reproducibility, the process is straightforward. Even beginners can configure these settings effectively thanks to the intuitive interface.
