[Genome] mm6 conservation

[thereal sisterdot]

Dear UCSC helper...

i have a question concerning the conservation track in the ucsc browser...
exporting the conservation data from either hgdownload and hgtable as a
custom track does not give me the exact same picture as in the conservation
track...
please see the example:
http://mendel.imp.ac.at/home/tmp/ucsc_phastcons_howto.gif

can you please advise me how the data [0.0...1.0] as in
http://hgdownload.cse.ucsc.edu/goldenPath/mm6/phastCons10Scores
can be converted to obtain the desired view...

thanks,
sisterdot
