Global Natural Products Social Molecular Networking (GNPS, is a web-based mass spectrometry ecosystem that aims to be an 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 700 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.
