System, method, and computer program product using a database in a computing system to compile and compare metabolomic data obtained from a plurality of samples
View Patent ↗The present invention generates a visual display of metabolomic data compiled by a database and associated processor. More particularly, the present invention provides a database for automatically receiving a three-dimensional spectrometry data set for a group of samples. The present invention also provides a processor device for manipulating the data sets to produce plots that are directly comparable to a plurality of characteristic plots corresponding to a plurality of selected metabolites. Furthermore, the processor device may generate a visual display indicating the presence of the selected metabolites across the group of samples. Thus, the present invention enables a user to analyze a series of complex data sets in a visual display that may indicate the presence of the selected metabolites across the group of samples. Furthermore, the visual display generated by embodiments of the present invention also expedites the subjective analysis of the spectrometry data sets.
