Figure 1From: Analysis of mass spectrometry data using sub-spectraExamples of sub-spectra. (a) Example of differences in the amount of signal and noise in sub-spectra resulting from measurements at different spot positions. The spot positions are indicated on the right. (b) Examples of a peak corresponding to ubiquitin (mass indicated by red dotted line) in two sub-spectra and the full (aggregated) spectrum.Back to article page
