Figure 3

Heatmap of the metagene matrix. The metagene matrix was obtained from the same factorization used in Figure 2. Each row corresponds to a gene. The most metagene-specific genes were selected using the Kim and Park's scoring and filtering method. This resulted in the selection of 635 genes. Rows were scaled to sum to one and ordered by hierarchical clustering based on the euclidean distance and average linkage.
