Fig. 13. Histograms of concentration values predicted by our algorithm (Upper) and Affymetrix MICROARRAY SUITE 5 (Lower) for all data at spike-in concentrations of 1 pM (Left) and 4 pM (Right). Only concentration values predicted to be nonzero by our algorithm (Upper) or corresponding to genes called as "present" by MICROARRAY SUITE 5 (Lower) are included in the histograms.
