filters centroided data for peak patterns
The algorithm searches for patterns of multiple peptides in the data. The peptides appear as characteristic patterns of isotopic peaks in MS1 spectra. We search the centroided data for such patterns. For each peak pattern the algorithm generates a filter result.
