Search one MS/MS spectrum against all public GNPS/MassIVE data with fastMASST, then see which foods it was observed in: the file-level hits are mapped to their food source and rolled up onto the foodMASST reference tree. The search runs on the GNPS server; the join and tree run in your browser.

Only lineages with matches are shown. Circle size scales with matches in the subtree; colored nodes are the exact food types that matched. Click a node to collapse or expand its branch.

fastMASST matches fragmentation patterns; a hit means a public spectrum looks similar
to your query, not a confirmed identification — verify with the mirror plot.
Food assignments come from the curated
foodMASST
reference table (public MassIVE files annotated to food types); only hits in files
that table covers appear in the tree. One matched file is counted per node at its
best cosine (mirroring upstream). Search runs on api.fasst.gnps2.org and needs
cross-origin access enabled there for apps.gnps2.org, else it fails with a
network error.
