 - (FC) Control of fold change plot: For both input m/z a zoomed in average spectrum is drawn with the input m/z as blue dashed line, the m/z range as blue dotted lines and the maximum intensity in the m/z window with a red line. 
-- (FC) Fold change image: For each spectrum the intensities of the two optimal m/z features (red lines in control plots) are divided and log2 transformed to obtain the fold change, which is then plotted as a heatmap. 
+- (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. 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.

 - Median intensity: For each spectrum the median intensity is plotted as heatmap. 
+- Maximum intensity: For each spectrum the maximum intensity is plotted as heatmap. 
 - Most abundant m/z in each spectrum: For each spectrum the m/z value with the highest intensity is plotted. 
-- PCA for two components: Result of a principal component analysis (PCA) for two components is given. The loading plot depicts the contribution of each m/z value and the x-y image represents the differences between the pixels.
