 - (FC) Fold change image: For each input m/z the average intensity within the given ppm range is calculated, then the log2 fold change of both average intensities is taken and plotted as heatmap. 
 - (cal) Intensity heatmaps for the m/z value that is closest to the calibrant m/z (can be outside the ppm range). The intensities are averaged within the calibrant m/z window (ppm range). 
 - Number of peaks per spectrum: For each spectrum the number of m/z values with intensity > 0 is calculated and plotted as heatmap.
-- Total ion chromatogram: For each spectrum all intensities are summed up to obtain the TIC which is plotted as heatmap.
