Histogram of coSI values (left) and boxplots of coSI values in bins according to the distance of an exon to the annotated polyA site (intervals on x-axis give minimum and maximum distance in each bin; right) for the total chromatin-associated RNA fraction (A), the polyA− nuclear fraction (B), the polyA+ nuclear fraction (C), and the polyA+ cytosolic fraction (D). P-values were calculated comparing the first and the last bin, using a two-sided Wilcoxon rank sum test. Numbers below boxplots indicate the median value of the according distribution.
