Figure 3.

Two histograms showing the distributions of the CM score in the ±500 bp flanks of HNF4α sites (gray bars) versus ±500 bp flanks of PWM matches (PWM score >0.8) in random genomic positions (white bars). The average CM score for real HNF4α sites is 0.499, whereas for PWM matches in random genomic positions (in the set N_Global) it is 0.050 (ratio = 9.98, t-test p-value = 1.4896 × 10^-26).
