All of the statistical evaluations were done and visualized in
GeneXPress, a cluster analysis and visualization tool
we developed for this purpose. The tool can evaluate the output of any clustering program for
enrichment of gene annotations and motifs and is freely available for academic use.
After downloading GeneXPress, you can examine all modules
in detail, by opening the full expression compendium
in GeneXPress (this file is very heavy and requires machines with 1GB RAM). You can also download the raw expression data in GeneXPress format. We wrote a brief tutorial of GeneXPress for the purpose of this analysis.
