Drosophila melanogaster Gene Expression Scores
These expression levels are derived from RNA-seq data from the Celniker group
and are log2 of the actual value.

This heatmap shows estimated expression levels for annotated genes, using signals from Affymetrix Drosophila tiling arrays. The arrays were hybridized with total RNAs extracted from 25 cell lines and 30 developmental stages. The original gene scores table provides expression scores for all genes listed in the FlyBase version 5.12 annotation. Each gene was assigned a score equal to the maximum exon score for all the exons associated with the gene in the annotation. That is, we made no effort to derive distinct scores for known isoforms. [Note: Some exons are annotated as components of more than one genes. Such exons are represented in more than one row, with different values for geneID, geneName and FBgn.] IMPORTANT: Hybridization efficiencies vary significantly from probe to probe and exon to exon. Consequently, the data in these tables are useful for comparing a single gene in multiple RNA samples (i.e. you may compare scores within a row). But they are NOT useful for comparing different genes or exons from a single RNA sample (i.e. do NOT try to compare scores within a column).
