This track shows expression data from GNF (The Genomics Institute of the Novartis Research
Foundation) using Affymetrix GeneChips. The chip types, chip IDs or tissue
averages associated with experiments can be displayed by selecting the
appropriate option from the Experiment Display menu on the track
description page. For more information, see the Track Configuration section.
For detailed information about the experiments, see Su et al. 2002
in the References section below. Alignments displayed on the track correspond
to the target sequences used by Affymetrix to choose probes.
In dense display mode, the track color denotes the average signal over all
experiments on a log base 2 scale. Lighter colors correspond to lower
signals and darker colors correspond to higher signals. In full display
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

This track may be configured to change the display mode and colors or
vary the type of experiment information shown. The configuration controls are
located at the top of the track description page, which is accessed via
the small button to the left of the track's graphical display or the link
on the track's control menu.
