Transcriptome data for chromosomes 21 and 22 from Affymetrix as described in " "Large-Scale Transcriptional Activity in Chromosomes 21 and 22", Kapranov, P., Cawley, S. E., Drenkow, J., Bekiranov, S, Strausberg, R. L., Fodor, S.P.A. and Gingeras, T.R.. In general data presented is the perfect match - mis-match value. Different experiments were normalized by setting the average value to be the same for each chip. Replicates for different cell types were averaged together to produce the data seen in "full" mode for each cell type. In dense mode, or at the top in full mode, can be seen the maximum value over all experiments for that probe called "Transcriptome". The idea being to paint as many transcribed regions as possible.
