MASST: A Web-based Basic Mass Spectrometry Search Tool for Molecules to Search Public Data

Abstract

Correspondence We introduce a web-enabled small-molecule mass spectrometry (MS) search engine. To date, no tool can query all the public small-molecule tandem MS data in metabolomics repositories, greatly limiting the utility of these resources in clinical, environmental and natural product applications. Therefore, we introduce a Ma ss S pectrometry S earch T ool (MASST) ( https://proteosafe-extensions.ucsd.edu/masst/ ), that enables the discovery of molecular relationships among accessible public metabolomics and natural product tandem mass spectrometry data (MS/MS).
