1. Evaluation of the novel peptides derived from MS/MS data.
Evaluation of the novel peptides derived from MS/MS data.A, The overall scoring integration of the novel peptides identified by three search engines. The axis in the three-dimensional scatter plot stand for -log 10 (Posterior Error Probability) values from X!Tandem, MS-GF+ and MyriMatch, respectively. The color points represent the normal peptides (red), the novel peptides (blue) and the excluded peptides including decoy peptides and peptides with FDRScore over 1% (green), respectively. B, The distribution of FDRScores for the peptides with density plots. The color curves have the same meaning as described in A. C, The distribution of matched ions for b, y and b-y pairs with bar plots. The colors represent the same meaning as described in A (ions from excluded peptides are not shown).
