Good Morning Emma: Please note the message in the table browser output:
# This data has been compressed with a minor loss in resolution. # (Worst case: 0.00489844) The original source data # (before querying and compression) is available at # http://hgdownload.cse.ucsc.edu/downloads.html The table browser does not display the original values. You use the download files for the exact original values.

For example for chr21 for the 10 first bases: track type=wiggle_0 name="Mammal Cons" description="Placental Mammal Conservation by PhastCons" # output date: 2011-09-20 13:25:03 UTC # chrom specified: chr21 # position specified: 9411194-9411294 # This data has been compressed with a minor loss in resolution. # (Worst case: 0.00489844) The original source data # (before querying and compression) is available at # http://hgdownload.cse.ucsc.edu/downloads.html variableStep chrom=chr21 span=1 9411194 0.0493701 9411195 0.0394961 9411196 0.029622 9411197 0.014811 9411198 0.00987402 9411199 0.00493701 9411200 0.00987402 9411201 0.019748 9411202 0.024685 9411203 0.0345591 whereas: fixedStep chrom=chr21 start=9411194 step=1 0.053 0.044 0.033 0.017 0.010 0.008 0.011 0.020 0.025 0.039 Am I missing something?
