Summary statistics of K562 RNAPII ChIA-PET dataset (Replicate 1) generated using the plotSummaryStats function from GenomicInteractions. K562 ChIA-PET data for PolII (8WG16) was taken from Li et al. [21] and filtered as described in the associated text. a Number of cis/trans interactions b Donut plot of number of interaction classes (promoter—2.5 kb around an Ensembl gene TSS, r—repressed region, e—enhancer or weak enhancer, t—transcribed region) c Distribution of interaction distances between anchor regions. d Number of reads supporting each interaction
