filters centroided and profile 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 first search the centroided data, and optionally in a second step the spline interpolated profile data. For each peak pattern the algorithm generates a filter result.
