There is evidence of transcriptional activity for 32 out of 36 well-characterized lncRNAs using the Zipper plot. a Zipper plot and associated statistics for the set of 36 well-characterized lncRNAs proposed by [4] using CAGE-seq data. Even though the visualization contains a +/− 5 kb window, it is clear that the closest CAGE peaks for 26 lncRNAs are within +/− 2.5 kb from the TSS. Both AUZ_right_pval and AUZ_left_pval are smaller than 0.01, suggesting that the set of TSSs are more closely associated with CAGE peaks compared to random regions in the genome. b Heatmap showing the distance between TSSs and CAGE-seq, DNase-seq, H3K4me1, H3K4me3 and H3K27ac peaks. Darker colours represent peaks that are closer to the TSSs. LncRNAs marked with an asterisk do not have enough evidence of transcriptional activity. (nt = nucleotides)
