Four Way Venn Analysis of Active Genes. Each data set was converted into ortholog space and processed for activity using relaxed criteria prior to analysis using the 4-way Venn Diagram Generator http://www.pangloss.com/seidel/Protocols/venn4.cgi. The Venn set was subsequently filtered for genes which met the initial, high-stringency criteria to ensure robust comparisons. Gene lists for each Venn set are available [see Additional File 7].
