Fig. 3From: Transfer posterior error probability estimation for peptide identificationExamples of linear fitting results of a γG(x) and b λG(x) in the variant-peptide identification simulation study. The x-axis represents the score threshold, and the y-axis represents a the proportion of decoy variant PSMs among all decoy PSMs, or b the estimated proportion of correct variant PSMs among all variant PSMs above the score threshold xBack to article page
