Hi,

I'm working on getting a microarray track into our local mirror,
following directions from the wiki page I was able to do so.

The coordinates I was using initially were from this file:
http://www.affymetrix.com/analysis/downloads/na31/ivt/HG-U133_Plus_2.na31.annot.csv.zip

But this coordinates expand very large areas, I would like to only
display data for the exon areas like in "GNF Atlas 2" track, I found I
could add "expDrawExons on" to activate this option, but after
selecting it I still don't get the same results, so I focus my
attention into getting blockCounts, blockSizes and chromStarts right,
I tried to take the coordinates for the probes from affyU133Plus2
track, that didn't do the trick either ask I could see the coordinates
in affyU133Plus2 and gnfAtlas2 aren't exactly the same, my last
resource was to use the coordinates directly from gnfAtlas2, but that
doesn't cover all of the probes we have. Is there a better way to get
this right?

Thanks for your help,
