Comparison of the similarity of the results of the methods of analysis. Illustrating, for a reference genelist, how far down another list of genes one would have to go to include 90% of the first x genes returned by the reference, where x is depicted on the x-axis. The genelists depicted are those associated with the six different analyses of the real data. Additionally, an analysis of the single (green) channel only from the ozone affected arrays is included. Note that one line in each plot compares the reference method to itself and so naturally has the equation y = 0.9x.
