Expression of Human Genes
The map shows all the Human exons for
which reliable gene expression correlations can be
calculated from GEO Affymetrix HG-U133 2+ GeneChip CEL files.
It can be searched

This links to exon-exon correlations,
correlation heat maps for probes within the same exon
and information about
the gene and its exons in Ensembl.
Its quite nice to use links in rnanet.html
to open gene_description.html in a separate windows.
