DreaMS Search provides easy access to spectral library searches to identify small molecules or their analogue candidates by querying the MassSpecGym spectral library (a combination of GNPS, MoNA, and Pluskal lab data) or custom MS/MS datasets. It is powered by DreaMS (Deep Representations Empowering the Annotation of Mass Spectra), a transformer-based neural network designed to interpret tandem mass spectrometry (MS/MS) data (Bushuiev et al., Nature Biotechnology, 2025).
