Welcome to GNPS Documentation

Global Natural Products Social Molecular Networking (GNPS, is a web-based mass spectrometry ecosystem that aims to be an open-source and open-access knowledge base for community-wide organization and sharing of raw, processed or identified tandem mass (MS/MS) spectrometry data. GNPS aids in identification and discovery throughout the entire life cycle of data; from initial data acquisition/analysis to post publication.

As there are many aspects to GNPS, it can be a bit overwhelming. Here is a quick description of main functionalities:

Analyze and Annotate

Share and Explore

  • Publish entire study datasets with the Mass Spectrometry Interactive Virtual Environment (MassIVE) data repository (Dataset Submission).
  • Browse and Reanalyze over 1500 public datasets at GNPS
  • Automatic reanalysis of public datasets with automated reports of new identifications (Continuous Identification).
  • Explore identifications of public datasets across entire repository (Molecule Explorer).

For more detailed information, read on in the documentation, checkout the GNPS publication, and view some tutorial videos.

GNPS Documentation Site Authors

We would like to thank the following contributors to the documentation.

However, we want to acknowledge that we have moved documentation in 2018 to GitHub from our previous wiki and those contributions are not reflected in these numbers and were broadly subsumed into Ming Wang's contributions. These first additions to the documentation were invaluable and a few of those pioneers were Vanessa Phelan, Laura Sanchez, Laura Pace, Alexey Gurevich, and Don D. Nguyen.
