Figure 7

Two-dimensional supervised cluster analysis using 43 samples and 51 genes. The cluster showed significantly different copy-numbers from 5 comparisons: stable vs. intermediate, stable vs. unstable, intermediate vs. unstable, stable/intermediate vs. unstable, and stable vs. unstable/intermediate. The statistical data from these comparisons are shown in Additional file 1: Table S5. The clustering results of samples were very similar to those of Figure 5; the samples were classified into 3 clusters: stable, intermediate, and unstable, which are marked with grey, yellow, and pink frames, respectively.
