The tool normalizes the intensities of a set of maps (consensusXML file). The following normalization algorithms are available:

  • Robust regression: Maps are normalized pair-wise relative to the map with the most features. Given two maps, peptide featues are classified as non-outliers (ratio_threshold < intensity ratio < 1/ratio_threshold) or outliers. From the non-outliers an average intensity ratio is calculated and used for normalization.
  • Median correction: The median of all maps is set to the median of the map with the most features.
  • Quantile normalization: Performs an exact quantile normalization if the number of features is equal across all maps. Otherwise, an approximate quantile normalization using resampling is applied.
