Histograms of fold change calculations on two human lung sample replicates. The two hybridizations obtained from the same mRNA source are supposed to have identical gene expression levels. The MAS4 and MOID calculations are in blue and red bars, respectively. The fold change values for MAS4 and MOID are shifted slightly to the left and right, respectively, to avoid overlapping. 80 percent of data are distributed in the range [0.80, 1.34] for MAS4, and [0.92, 1.22] for MOID. Only genes marked as "Present" by MAS4 were counted in the histogram. If all genes are taken into account, 80 percent of data are distributed in the range [0.59, 1.48] for MAS4 and [0.96, 1.25] for MOID.
