Figure 7. Two heatmaps of expression values of genes analyzed by the proposed algorithm from the normal human tissue dataset: (A) a heatmap of expression values of genes in Cluster C18, and the heatmap shows similar expression patterns of genes in different samples, (B) a heatmap of expression values of genes in Cluster C3, and the heatmap shows different expression patterns of genes in different samples (denoted as a and b).
