(A) Scatterplot matrix demonstrating cluster formation within tumor types when divided by the five basis spectra. Clusters within the scatterplot were magnified, emphasizing regions of higher data density. The diagonal shows the distribution of the respective abundances of the basis spectra for each tumor subtype. (B) Scatterplot of different tumor types and their distribution among [PpIX620] and [PpIX634].
