ppm |
numeric the ppm mass error acceptable before a new ROI is initialized. This ppm is allowed on both sides of the mass. |
prefilter |
numeric a two integer vector. The first indicates the minimum number of peaks an ROI must contain to be retained. The second indicates the minimum intensity those muct be. |
maxskip |
integer The number of scans an ROI must not contain a peak before clossing the ROI. This is an addition to the original algorithm. Useful for QE data. |
