Fig. 4. Evaluation of searching blocks against those of BMDMS-NP. Blocks in (A) and (C) are from NIST17 and those in (B) and (D) are from MoNA. Lines marked with 'x' in (C) and (D) show the performance after application of precursor m/z filter had been adopted prior to calculation of the similarity score between blocks.
