Table 2 Scores calculated using spectra library SL

From: Spectra library assisted de novo peptide sequencing for HCD and ETD spectra pairs

Feature Score calculation
Amino acid difference \(S^{aa}_{SL}=\frac {1}{L}\sum ^{k=L}_{k=1}S^{ion}_{k}\)
Ion complementarity \(S^{comp}_{SL}=\frac {1}{L}\sum ^{k=L}_{k=1}S^{comp}_{k}\)
