Fig. 6. — Identification of multiple precursor ions in mixed tandem MS spectra. A, an example to show two co-isolated ions within the isolation window. The percentage of precursor intensity (PPI) is calculated for all precursors within the isolation window. B, inclusion of multiple precursors for the same MS/MS spectra allowed more identification than the selection of only one precursor. The cutoff was set at 1% FDR. C, D, the distribution of target and decoy PSMs along matching scores for the top precursors and for the remaining precursors.
