From: Increasing peptide identifications and decreasing search times for ETD spectra by pre-processing and calculation of parent precursor charge

Figure 6

Combined improvement by updating the precursor filter, noise filter and estimating precursor charge state. This ROC plot shows the improvement in sensitivity of peptide identifications by employing different kinds of spectral pre-processing steps. Overall, there is a 18.8% increase in identifications at 1% FDR with the new precursor and noise filters and using charge assignment, when compared to the older filters in OMSSA using range search method.
