Abstract:
1. A system for reassembling assembled peaks in a composite digital image representing liquid chromatography or mass spectrometry data, the system comprising: a peaklets assembler configured to form an assemblage of peaks in the composite image by identifying a seed peak having a first mass/charge ratio and identifying other peaks adjacent to the seed peak that each have a mass/charge ratio within a calculated tolerance from the first mass/charge ratio, each peak in the assemblage having a likelihood of representing the same biological feature of interest; and a peaks reassembler configured to revise the assemblage by creating chromatograms from replicates that form the composite image in a defined image region that contains the assemblage, the peaks reassembler reassembling peaks to indicate that the peaks represent the same biological feature of interest when a computed bi-directional complementation strength together with a computed unidirectional complementation strength is greater than a computed collision strength, wherein bi- and uni-directional complementation strength indicate a likelihood that peaks represent the same biological feature, and collision strength indicates a likelihood that peaks represent distinct biological features.
