Gene cluster comparison for indivdual tissues in the single matrix, “,” with the four separate tissue matrices “.”

H1, SM1, L1 and K1 are the gene clusters most characteristic for the heart, skeletal muscle, liver and kidney, respectively, in the single (combined) data set, as in Figure 2. Clust.1, 2, or 3 denotes the 100 genes most securely placed within the clusters of the diferently ordered genes in the 4-way factorization shown in Figure 5. The order of the clusters is 1–3, from the top of the figire, for each tissue. We refer to these clusters as “,” etc. The overlap of the from the one-way factorization to is referred to as cluster 1.
