Figure 6: ROC method plots (SN vs. 1-SP*) of average minimum peptide probability of all consensus methods tested. ROC characteristics were plotted for A) all consensus methods, B) individual (O), C) the intersection (I), and D) the union (U) consensus methods filtered at a set average minimum protein probability used as a search constraint. The minimum peptide probability values used were 0%, 20%, 50%, 80%, 90%, and 95%.
