Interplatform agreement. The descriptive CAT (Correspondence At the Top) plots [9] were used to evaluate interplatform agreement. The Correspondence at the top was evaluated for AFFX and ABI using the full set of genes after the IQR filtering step (black line) or after the IC filtering step (red line). For each of the two platforms average |log2 (Fold Change)|, calculated between treatment vs. control group, was used to generate CAT Plots.
