Figure 2. Dendrogram classification of the original mice (17 WT & 13 R6/2) according to unsupervised HCA.
Rows #1–17 are the WT mice, whereas rows #18–30 are the R6/2 mice. Looking at the area where there are only two clusters (Dissimilarity range of ~ 1.63–2.26), one can see that subject #30 was classified into one cluster all by itself, and that all other 29 subjects were classified into the other cluster. This classification makes little sense.
