Epigenetic signals for DNase I hypersensitivity, histone variant H2A.Z, and 10 histone modifications along colocalized retrocopies, noncolocalized retrocopies, and unprocessed pseudogenes and their flanking regions (±3 kb) in the GM12878 cell line. Solid lines represent the mean fold change signal, and shadowed areas denote the standard error. TSS, putative transcription start site; TES, putative transcription end site.
