  1. The "Denoised" spectra can be identified only after denoising. The "Overlap" spectra can be identified from both the denoised and the raw spectra. The "Raw" spectra can be found only in the original undenoised spectra. "Total" counts the sums. "FP " are the false positives in the identified spectra, and "TP " are the true positives in the identified spectra.
