Predicting spectra intensity pattern: on peptide GYSFVTTAER. Figure 5-A: The raw MS/MS data of peptide GYSFVTTAER. Unlabeled green peaks are ions degraded from labeled b/y ions by losing H₂O, NH₃, etc. Figure 5-B: The comparison of the experimental spectrum (red) versus the spectrum predicted by the network model (blue). The experimental spectrum is the y-ions extracted from the raw data (Figure 5-A) with intensities log-transformed. Figure 5-C: The effect of using probability theory. Blue dots indicate the interval [mean intensity - SD, mean intensity + SD] within which intensities of the ions are supposed to lie.
