For each investigated cell line (first column), we reported the number of compiled TF ChIP-Seq experiments (second column) and DHS and histone modification data sets (third column). The corresponding total number of TF ChIP-Seq peaks was given in the fourth column. Finally, we provided the number of heterozygous sites supported by at least 10 reads within the ChIP-Seq peaks (fifth column) and the number of ASB events (sixth column). Note that the numbers were derived from the compilation of all the TF ChIP-Seq data for each cell line. Details for each TF can be found in Supplementary Table S2.
