Abstract:
1. One or more computer-readable memory devices configured to store instructions, the instructions comprising: one or more instructions, executable by at least one processor to generate a first signal comprising a first spectrum of data including pulses centered at a plurality of reference peaks; one or more instructions, executable by the at least one processor to map, based on an objective function, a first plurality of mass-to-charge ratios associated with the pulses included in the first signal, to a second plurality of mass-to-charge ratios associated with pulses included in a mass spectrum signal, to maximize a value of a cross-correlation of the first signal to the mass spectrum signal; and one or more instructions, executable by the at least one processor to detect, based on mapping the first plurality of mass-to-charge ratios to the second plurality of mass-to-charge ratios, a structural transformation of a substance that is present in a sample, associated with the first signal.
