Title:
SECOND-ORDER METABOLIC MASS SPECTROMETRY COMPOUND DETECTION METHOD, STORAGE MEDIUM, AND SERVER
Document Type and Number:
WIPO Patent Application WO/2020/000500
Kind Code:
A1
Abstract:
A second-order metabolic mass spectrometry compound detection method, a storage medium, and a server, comprising: using an existing second-order metabolic mass spectrometry database as a basis, performing an operation of constructing a visual network on second-order mass spectrometry data of each compound; when inputting a multi-compound spectrum, using the range of the mass-to-charge ratio (m/z) of each compound in a database as a respective search range on the multi-compound spectrum, then performing an operation of constructing a visual network on a mass spectrum within said range; determining maximum sub-graph isomorphism for the visual network on the compound spectrum within said search search range and a visual network of a single compound spectrum in the database, and according to the foregoing, determining a similarity score, and determining whether said compounds are present.
