To: Peter Cote <[email protected]>


I think I know where your problem was:
first, do the "intersection" (actually: a union) of the two tracks with OR
and do NOT invert them yet. Create a new custom track using this called
"union".

Then goto the table browser again, select the "union" track, intersect it
with itself, operation is "OR". Now select the two inversion checkboxes.
create a new track "intergenic".

Here is what I got:
http://www.genome.ucsc.edu/cgi-bin/hgTracks?hgsid=160605701&db=hg18

does this work for you?

cheers
Max
