Heatmap view of the unsupervised clustering of 670 patients with glioma with expression profiles of the 104-gene group (TCGA samples). In the heatmap, the Y-axis represents the 104 genes and the X-axis represents patients with glioma. The expression levels from low to high are represented as a color gradient from green to red, respectively. There are three color bars of the heatmap utilizes different colors to represent IDH status (wild type and mutation), risk group (high/low), and patients with LGG and GBM
