Expression summary as reported in the SGD Expression Connection tool. For each gene (depicted by different color lines), the pattern that is reported in this figure is a copy of the "expression summary" histogram that was obtained using the Expression Connection tool from the SGD server http://www.yeastgenome.org. This graph indicates the number of samples (also called 'experiments' on the SGD server), at a given expression ratio value, that could be found in all the microarray datasets stored on the SGD server (i.e. approx. 30 studies). The expression data reported on the axis are in log2 scale.
