OpenMS is a powerful open-source software platform for analyzing mass spectrometry (MS) data. Actively developed for over two decades, it enables reproducible workflows across diverse applications such as:

  • Bottom-up and top-down proteomics
  • Metabolomics
  • Structural biology
  • Oligonucleotide MS

With a rich library of algorithms and tools, OpenMS supports both experimental researchers and developers.

  • Ready-to-use workflows (e.g. OpenMS WebApps) simplify data analysis.
  • Customizable modules in C++ and Python (pyOpenMS) enable tailored solutions and seamless integration with machine learning, visualization, and statistical pipelines.

Deployment Options

OpenMS can be deployed in many ways:

  • Interactive use - graphical user interface and command-line tools
  • Custom scripting - Python (pyOpenMS) for rapid prototyping and integration with data science libraries
  • Workflow systems - integration with Nextflow, Snakemake, and KNIME
  • Scalable environments - optimized for desktop use, HPC clusters, and cloud deployments

Key Features

OpenMS is:

  • Open and interoperable - using HUPO-PSI open-standard file formats for maximum compatibility
  • Accessible - with modern documentation and Python support
  • Scalable - from single-PC use to cloud-based pipelines
  • Community-driven - built by 150+ contributors worldwide, openly available on GitHub under a permissive BSD license

In short, OpenMS empowers researchers to perform cutting-edge, reproducible MS data analysis - from individual experiments to large-scale, automated pipelines.
