Systems and methods for sample comparison and classification

摘要

A system includes a database server and a plurality of processing nodes. The plurality of processing nodes are configured to receive mass spectrometry data from a plurality of samples; align the mass spectrometry data to correct for changes in retention time to generate a reference alignment; cluster compounds across the plurality of samples; store the reference alignment and clustered compound data to the database server; receive additional mass spectrometry data from additional samples; align the additional mass spectrometry data to a reference alignment within the database; correlate the compounds from the additional samples with the clustered compound data; classify the compounds; perform statistical analysis on the classified compounds to identify compounds meeting threshold criteria; and provide an indication of compounds meeting the threshold criteria.
