RPKM range for 1 kb tiled genome windows, by biological replicate. For box plots, each box encloses the middle 50% of the distribution (25th percentile – 75th percentile, or interquartile range (IQR)). Lines in boxes mark medians. Lines extending from boxes mark minimum and maximum values that fall within 1.5 times the IQR. A. Outlier points excluded. B. Outlier points included. C.
