This track displays selected data from the GNF Expression Atlas on the Affymetrix U95 chip. It shows the ratio of expression of a gene in specific tissues to expression of the gene overall. By default, a gene that is more highly expressed in a tissue is colored red, and a less expressed gene is shown in green. This coloring is standard, but is the opposite of what a naive user might expect: in this case, red means go, and green means stop! Black means a gene is neither over nor under expressed in the tissue. Uncolored boxes (white on most browsers) represent missing data.
Color-blind users can switch the coloring from red/green to yellow/blue via the configure button.
