Extended Data Fig. 5: Validation of FDR estimation on reference MS/MS libraries.
From: BUDDY: molecular formula discovery via bottom-up MS/MS interrogation

We used four reference MS/MS libraries to evaluate FDR estimation in BUDDY. Q-Q plots of estimated FDR and exact FDR are shown. In both positive and negative ion modes, estimated FDR shows high Pearson’s correlation coefficients (r > 0.98) with exact FDR.
