Sample cluster of the pilot data set (A) and sample and gene cluster of the complete data set (B). The sample cluster dendrogram form the pilot data set (A) uses the average linkage clustering method and represents the most frequently occurring dendrogram out of the 40 derived for the data set. Horizontal distance indicates relatedness. The sample and gene cluster (B) from all 23 samples shows a colored representation of the gene expression data where columns are individual genes and rows are separate samples. The color in each cell of the table represents the median adjusted expression value of each gene.
