Figure 3. Comparisons of scores for partial and full tryptic searches.

Figure 3

Scores for the 710 spectra in a human serum data set that generated high-quality peptide matches in both the full or partial tryptic searches were compared. (A) The highest-scoring search method is indicated for each of the individual parameters analyzed (Xcorr, ΔCN, and mass accuracy). (B) Xcorr scores for doubly charged spectra. (C) Xcorr scores for triply charged spectra. (D) Distribution of ΔCN scores.
