Figure 4: A) Within and between group euclidean distances based on MALDI-TOF mass spectra. B) PCA of hellinger-transformed mass spectra. C) TSNE plot of RF model generated with three classes (I-III, IV and V). Specimens in B) and C) are colored according to the respective groups. Symbols indicate the respective sex. D) Relative intensities of peaks which are important for group differentiation. A mass shift between I-III and IV-V was observed in peaks >10kDa.
