aThe table shows (for each TF) the total number of peaks identified by each peak-finder (including the number of peaks common to all methods), the number of peaks used for GREAT analysis (including the number of common peaks), the number of associated genes identified by GREAT, and the binominal FDR Q-values identified by GREAT for the selected GO and TF-associated terms. The smallest Q-value for each term is shown in bold.
