This dataset was generated by Venkat Chintapalli, Jing Wang & Julian Dow at the University of Glasgow with funding from the UK's BBSRC.
It gives you a quick answer to the question: where is my gene of interest expressed/enriched in the adult fly?
For each gene & tissue, you're given the mRNA SIGNAL (how abundant the mRNA is), the mRNA ENRICHMENT (compared to whole flies), and the Affymetrix PRESENT CALL (out of 4 arrays, how many times it was detectably expressed).
