Removal unidentifiable spectra by msmsEval. The predicted fraction of spectra removed for identifiable (â—†) and unidentifiable (x) spectra were plotted against the observed fractions for 10 runs of the UCD test dataset (A) and 22 runs of the ISB test dataset (B). The estimated fraction of spectra removed is calculated by taking the respective percentiles from the identifiable spectra Gaussian distributions. The diagonal thin dashed line shows expected trend for the removal of identifiable spectra if the estimated values match the observed values perfectly. Error bars are one standard deviation from the average of the respective test datasets. Receiver operator curves showing the fraction of identifiable spectra removed versus unidentifiable spectra removed for the UCD test dataset (solid line) and ISB dataset (dashed line) are also shown (C).
