I'm starting conservation analysis with phyloP score by UCSC Genome Browser.
They provide phyloP score here: "hgdownload.soe.ucsc.edu/goldenPath/hg19/phyloP100way/"
However, the score is a little bit different from that of score seen by UCSC Genome Browser.
For example, a position chr6:46721460 in the Genome Broswer is denoted as 0.0046... but in the wig data (you can download via the above link) the same position has a value of 0.035. Of course, the discrepancy between them is not much big (maybe it can be acceptable to determine conserved region... in my thought); I still want to know the reason why.
If there is anybody knows about it, please reply.
Thanks for your attention.
