Good Morning Itamar: Please note the discussion of precision in the wiggle format: http://genome.ucsc.edu/goldenPath/help/wiggle.html

You can avoid this loss of precision and improve the efficiency of display of your tracks with the bigWig format instead: http://genome.ucsc.edu/goldenPath/help/bigWig.html --Hiram itamar simon wrote: > I uploaded a custom track to the genome browser using the human HG18 > release and the wiggle format.
