Filtering genes or metagenes by differential expression: Different numbers of metagenes (left mosaics) and single genes (right mosaics) are selected using the FC-1000/FC-3600 (a) and FC-100/FC-1000 (b) filters to account for the data compression in the metagene clusters. The brown areas in the left part show the selected metagenes and the colored tiles in the right part the fraction of single genes in the metagene miniclusters (maroon to blue codes high to low fractions). The Venn-diagrams illustrate the degree of overlap between the metagenes and single genes selected by both filters.
