This tool performs precursor m/z correction on picked (=centroided) high resolution data.

Three methods are available: 'nearest_peak', 'highest_intensity_peak' and 'feature'.

  • nearest_peak: Use nearest centroided MS1 peak for precursor mass correction.
  • highest_intensity_peak: Use highest intensity centroided MS1 peak in a given mass range for precursor mass correction.
  • feature: Use features for precursor mass correction, which allows for charge correction.

The method hightest_intensity_peak searches in a specific m/z-window of the precursor information for the peak with the highest intensity. Suggestioned value 1/maximal expected charge. E.g maximal expected charge 5, m/z-window = +/- 0.2 Da

See the corresponding parameter subsection for details.
