Figure 2From: A novel scoring schema for peptide identification by searching protein sequence databases using tandem mass spectrometry dataOccurrence probability of different N-terminal ions. In general, serial ions bear a larger probability, however, their variants (like dehydrated form) also often appear. The m/z of the peptide bond is set to 0, and the relative probability is normalized to a total probability of 100.0 (including C-terminal ions, which are not shown).Back to article page
