Fig. 1.

Heat map display. Class clustering was performed using the detected peaks and is presented as a heat map. The horizontal axis shows the sample names and the vertical axis shows the peaks. The distance between peaks is denoted by the tree shape in the figure. Peaks smaller than the average are shown in deep green, and those that are larger than the average are deep red. The data were standardized by substituting ε (= 0) for N.D. (μ = 0, σ = 1)
