Classification of samples by SOM analysis and K-means clustering. SOM component planes are shown for a) 42 DLBCL samples and three DLBCL cell lines (OCILy3, OCILy10 and OCILy1). SOM map size is (22 × 14) and the color scale of SOM component plane represented the mean ratio in each map node, and red indicates high expression, blue indicates low expression. See supplementary information for full data. b) K-means clustering of SOM, mean SOM component planes for DLBCL, FL and CLL. The cluster numbers are given, and the genes contained within each SOM node and K-means cluster are listed in the web supplement [13], selected genes from clusters 10, 11 and 1, 7, 9 are listed in table 1.
