Correlation among histone marks. K-means clustering (k = 2) of rank orders for ChIP enriched DNA/input ratios of individual histone marks in male and female adult flies. X chromosome genes (top) and autosome genes (bottom) are clustered separately. The order of ChIP samples was fixed as indicated in the figure. Genes enriched for histone marks (yellow) and genes depleted for histone marks (blue) are indicated.
