## Description

This track shows expression data from GNF (The Genomics Institute of the Novartis Research Foundation) using the Affymetrix U74A chip.

## Methods

For detailed information about the experiments, see Su et al. (2002) in the References section below. Alignments displayed on the track correspond to the consensus sequences used by Affymetrix to choose probes.

In dense mode, the track color denotes the average signal over all experiments on a log base 2 scale. Lighter colors correspond to lower signals; darker colors correspond to higher signals. In full mode, the color of each item represents the log base 2 ratio of the signal of that particular experiment to the median signal of all experiments for that probe.

More information about individual probes and probe sets is available at Affymetrix's netaffx.com website.
