Fig. 2From: A graph-based approach for proteoform identification and quantification using top-down homogeneous multiplexed tandem mass spectraComparison of the numbers of matched fragment ions. The numbers of matched fragment ions are compared for the 184 spectra identified by both the proposed method and MS-Align-E. For each spectrum, the difference between the number of fragment ions matched to the proteoform pair reported by the proposed method and that matched to the single proteoform reported by MS-Align-E is computedBack to article page
