Hierarchical clustering of gene expression datasets. Hierarchical clustering of 78 CRC samples in training and test sets which graphically displays the intensity of the gene expression for each gene. Samples were clustered based on the 19 significant genes. The color of each square boxes represents the ratio of gene expression. Red boxes indicates up regulated genes while green boxes represents down regulated genes. The column represent individual tissue samples while rows represent individual of genes
