FIG. 1

Normalized intensity distribution (before log10 transformation) of low-mass peaks in m/z regions between (I0, …) and near singly charged b (b1, …) and y (y1, …) ions from training spectra for peptide DLATVYVDVLK. Average peak frequency, per spectrum, in each m/z region is indicated above each normalized intensity box-plot.
