Figure : Visualization of the number of spectra in the GNPS library affected by the different filters. The central stacked bar graph splits the spectra into 3 groups. The orange group represents spectra that were completely removed by a filter, since they did not pass a metadata requirement. The blue group represents spectra that were repaired by at least one of the newly added repair functions focused on repairing the annotation. The grey group represents all other spectra, for which the metadata was harmonized, but the annotation or metadata was not affected by the newly added filters. The three horizontal bar graphs show how many spectra were affected by each filter within the 3 different groups, i.e., for metadata harmonization (left), repaired annotation (right top), and removed spectra (right bottom). It is important to note that a spectrum can be affected by multiple different filters during a full pipeline run.
