**What it does**
This tool uses intersectBed to find intervals in the first dataset that overlap with intervals in the second dataset. To estimate the significance of the overlap, the first dataset is shuffled then intersect with the second dataset to generate a null distribution of the number of overlaps. The tool returns venn diagram plot, histogram of the null distribution, overlapped intervals from the first input, and the null distribution of overlaps.
