Fig. 4From: DISMS2: A flexible algorithm for direct proteome- wide distance calculation of LC-MS/MS runsHistogram of MS/MS spectra distances and corresponding ROC curve. Histogram (left) showing MS/MS spectra distances of spectra pairs with the same peptide annotation in DB.af (dark gray) and of the remaining spectra pairs with different peptide annotation in DB.af (light gray), for H1 vs. H2. ROC curve (right) showing performance of cosine distance as a binary classifier of same or different peptides for different thresholds cdis Back to article page
