[galaxy-user] Counting intervals in one file overlapping intervals in another file - what are the hidden settings?

Hi, I am using the "Count intervals in one file overlapping intervals in another file" tool (part of the bedTools package) to assess the number of RNA-seq reads that map back to a specific region. (I am using this on the Galaxy test server). I am finding that this tool returns many more reads than it should. In reading the bedTools manual, it seems like this tool is the "windowBed" tool and it actually has many more parameters that are not shown on the Galaxy interface. What are these (hidden) settings for these parameters that are not shown? Hopefully this can explain my incorrectly recorded reads. Thanks in advance. Cheers, Mo Heydarian
