-Of the tools in the **Operate on Genomic Intervals** toolbox, **Join** and particularly **Intersect** have the most promise.  Let's try **Intersect**.
+Although there are the bedtools (section **BED**) and a section **Operate on Genomic Intervals** offering promising tools, the simple **Intersect** tool under **Text Manipulation** appears sufficient.  Let's try **Intersect**.
