Gene structure signals from EST-validated gene models
in Daphnia pulex and Drosophila melanogaster,
showing standard expression scores (as deviation t-statistic from signal boundary),
and G+C sequence content.
Expression is from Nimblegen measurements for Daphnia and Drosophila,
and Solexa measurement for Drosophila. Sample size is approx. 4,000 genes
for each structure and species.
