Significantly over-represented GO terms for Alu and B elements.

In the interest of clarity of the presentation we only show GO terms at GO hierarchy level ≥6; the entire list of GO terms can be found in Supplemental Table S1. The colors in the columns labeled “Alu” and “B” show for each GO term whether it is associated with upstream (U), sense intronic (I+), or antisense intronic (I-) regions. Significant GO terms are considered those terms whose adjusted p-values are less than 0.01 (see Methods). The actual adjusted and unadjusted p-values for each type of element and for each region and orientation can be found in Supplemental Table S1. The GO terms are organized in such a way so that related GO terms are located as close as possible to one another (note that this is not an easy problem, since the GO hierarchy is not a tree).
