The overlap analysis of TF pairs in GM12878 and K562. The distribution of the overlap ratio for 1485 TF pairs in GM12878 ((a) for genome-wide and (d) for enhancer region) and K562 ((b) for genome-wide and (e) for enhancer region). The X-axis is the value of the overlap ratio, and the Y-axis is the number of TF pairs. c The distribution of the relative variation index IRV. The X-axis is the value of the relative variation index, and the Y-axis is the number of TF pairs. The left and right lines located the position with μ ± 2σ. And μ is the mean and σ is the standard deviation of the relative variation index IRV. f The scatter plot and the Pearson correlation coefficient of the overlap ratio for 1485 TF pairs between two cell lines. The X-axis and Y-axis are the overlap ratios of TF pairs in GM12878 and K562 respectively. Here RG and RK indicate the overlap ratios of TF pairs in GM12878 and K562 respectively
