MassSpecGym (MassSpecGym: A benchmark for the discovery and identification of molecules)

Introduced by Roman Bushuiev et al. in MassSpecGym: A benchmark for the discovery and identification of molecules30 Oct 2024 archive 2025-07-28

MassSpecGym provides three challenges for benchmarking the discovery and identification of new molecules from MS/MS spectra:

  • 💥 De novo molecule generation (MS/MS spectrum → molecular structure)
    • ✨ Bonus chemical formulae challenge (MS/MS spectrum + chemical formula → molecular structure)
  • 💥 Molecule retrieval (MS/MS spectrum → ranked list of candidate molecular structures)
    • ✨ Bonus chemical formulae challenge (MS/MS spectrum → ranked list of candidate molecular structures with ground-truth chemical formulae)
  • 💥 Spectrum simulation (molecular structure → MS/MS spectrum)
    • ✨ Bonus chemical formulae challenge (molecular structure → MS/MS spectrum; evaluated on the retrieval of molecular structures with ground-truth chemical formulae)

The provided challenges abstract the process of scientific discovery from biological and environmental samples into well-defined machine learning problems with pre-defined datasets, data splits, and evaluation metrics.

All 6 leaderboards whose dataset resolves to this page shown (sort by any header). "First row" is the archive's own first row at snapshot, in the archive's row order; nothing here re-ranks and metric direction is not asserted.

Papers archive 2025-07-28

4 shown of 4 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 4. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
