Question: Problem In Set-Up Of "Coverage" Operation

The "coverage" tool is a great addition to the set, but I think the
description is backwards from the execution.
The user selects:
The density of elements of Query: (call it query 1)
within Query: (call it query 2)
The explanation says:
"Return entire regions from query 1 that overlap query2, and append
two more fields at the end of the returned region: (1) the number of
nucleotides for each returned region from query 1 that overlap a
region from query 2 and (2) the percentage of the overlap for each
region of query1: ..."
What you get is actually the opposite of the explanation. You get
the regions from the 2nd query that contain regions from query 1,
etc. The selection tools have query 2 as the target for finding
elements from query 1, but the explanation treats query 1 as the
target.
I think the first choice should be query 1 and the second choice be
query 2. You could change the explanation, but I think it would be
better to change the selection display. In that case, you would have
something like:
Within Query: (pull down menu of choices for the target)
Find the density of elements of Query: (pull down menu of choices for
elements to find in the target).
Then the explanation will fit.
