Benchmark Test of Ion Trap Spectral Library in Analyzing Q-Star Collected Query Spectra. A. Ion-trap and Q-Star spectra of the same peptide ALLEVVQSGGK (Q9CWH6) were shown in a mirror image form. Despite a characteristic distinction between the two spectra, a strong correlation in b- and y- ion series was clearly present, giving a final score of 0.687. B. With the Q-Star test dataset, a search using an ion trap spectral library covered 55.4% of the spectral matches offered via a sequence database search workflow, as well as 77.8% additional unique matches. C. Library search covered 100% of proteins identified via a sequence database search and offered an additional 18.8% in protein identification.
