👩💻 I'm working on it, so please be patient.
nf-core/mdsimulations is a bioinformatics pipeline for running molecular dynamic simulations (MD) using GROMACS open-source software. This workflow enables researchers to perform standard protein simulations in a fully automated manner, with minimal configuration, on both local and high-performance computing (HPC) environments.
We are currently working on the following tasks:
- 🚀📆 Official release of the
nf-core/mdsimulationspipeline. - 🛠👩💻 Expanding the pipeline’s capabilities to include more analysis modules (e.g., RMSF, distances), and integrating specialized tools for membrane proteins and protein-ligand complexes.
- 📚📝 Generating a comprehensive test dataset.
The nf-core/mdsimulations pipeline automates a standard GROMACS MD simulation workflow. The major steps are:
- Input pre-processing: From the PDB structure, remove the missing atoms.
- Production run: Main subworkflow of the pipeline.
- Generation of molecular topology,
- System solvation, and ion addition to neutralize the system.
- Energy Minimization: Removal of steric clashes and relaxation of the initial structure.
- Equilibration: NVT (constant Number, Volume, Temperature) and NPT (constant Number, Pressure, Temperature) equilibration to bring the system to the desired temperature and density.
- Production MD: Execution of the main molecular dynamics simulation.
- Post-processing: Centering the protein and remove periodic boundary condition (PBC).
- Analysis: Preliminary analysis of the Root-Mean-Square Deviation (RMSD).

Note
If you are new to Nextflow and nf-core, please refer to this page on how to set-up Nextflow. Make sure to test your setup with -profile test before running the workflow on actual data.
Warning
Please provide pipeline parameters via the CLI or Nextflow -params-file option. Custom config files including those provided by the -c Nextflow option can be used to provide any configuration except for parameters; see docs.
For more details and further functionality, please refer to the usage documentation and the parameter documentation.
