Heat Map
The heat map gives a quick overview of how similar the MHC binding motifs are.
The scale corresponds to the distance between the alleles, where Red (0) is very similar and beige/white (1) is dissimilar.
On the left side and on the top of the matrix is two small trees depicting the hierarchical clusters of the MHC alleles.
On the right side and in the bottom of the matrix are the labels.
