Description
Takes a peak table and filters searches for black bar artifacts and lorentzian noise
findNoise returns the indices of peaks which are identified as noise
Usage
1
2
findNoise(peaks, int, resolution.calc, profxr, mirror.ppm = 2,
mirror.logintrat = 0.7, mirror.totintrat = 0.1)
Arguments
peaks
The peak table to filter for noise
int
The intensity at which to check around a peak for noise
resolution.calc
a function which accepts mass and returns the resolution
profxr
an xcmsRaw object containing the profile mode data from this experiment.
mirror.ppm
the ppm window in which to detect mirror artifacts
mirror.loginrat
the intensity window in which to detect mirror artifacts
mirror.totinrat
the maximum intensity relative to the tall peak which can be considered noise
Value
The indices in peaks which qualify as noise
