Abstract
A method of identifying a related peak set from MS1 spectra data is provided. An intensity peak is selected from MS1 spectra data generated for a sample by a tandem mass spectrometer. A peak location is identified for the selected intensity peak. An intensity score is calculated from the MS1 spectra data for each of a plurality of possible related peak locations based on an intensity value associated with each of the plurality of possible related peak locations. Whether or not any of the plurality of possible related peak locations forms a related peak set is determined based on the calculated intensity score for each of the plurality of possible related peak locations.
