From: Highly sensitive feature detection for high resolution LC/MS

Algorithm Number of detected MM14 features Number of other reported features Parameters
centWave 115 443 peakwidth = (5,10), ppm = 30, snthresh = 5, prefilter = (2,400)
matchedFilter 114 425 fwhm = 4, snthresh = 12, step = 0.02, mzdiff = 0, max = 50
MZmine 107 442 bin size = 0.05, chromatographic threshold level = 0.8, intensity tolerance = 0.7, minimum peak duration = 3, minimum peak height = 500, m/z tolerance = 0.03, noise level = 20
