Relative representation of ten different chromatin marks at predicted BEST loci in IMR90 cells. The natural logarithm (ln) of the fold-enrichment over background (y-axis) is shown for ten different histone modifications at high-confidence BEST predictions (brown), DHS+/H3K27ac+ regions (dark blue), and DHS+/H3K27ac- regions (light blue). Background regions are non-promoter, non-DHS, 2-kb windows randomly selected from the genome. Error bars represent the standard deviation among biological replicates.
