Histone marks are highly associated with gene expression levels in IMR90. Genes were divided into nine groups according to their expression levels. A HebbPlot was generated from the coding regions of each group. In general, a HebbPlot cools down — becomes bluer — as the expression level decreases. The more red a row is, the more consistent its mark is distributed around the set of regions. H3K36me3 and H3K79me1 mark the coding regions of active genes in IMR90, whereas the repressive modification, H3K27me3, marks the inactive coding regions. H2A.Z is ubiquitous. a First group, b Second group, c Third group, d Fourth group, e Fifth group, f Sixth group, g Seventh group, h Eighth group, i Ninth group
