This tools accepts a set of chromatograms and picks peaks in them, correctly grouping related transitions from the same precursor together. It will perform the following steps:

  • Step 1: find features (peaks) in individual chromatograms
  • Step 2: merge these features to consensus features that span multiple chromatograms

Step 1 is performed by smoothing the individual chromatogram and applying the PeakPickerHiRes.

Step 2 is performed by finding the largest peak overall and use this to create a feature, propagating this through all chromatograms.

This tool will not compute any scores for the peaks, in order to do peak picking please use TOPP_OpenSwathAnalyzer

The command line parameters of this tool are:
