[Genome] [Question] discrepancy of multiz17way score between the database and the browser

[mousheng xu]

Dear Genome Help,

If you do a ""select * from multiz17way where chrom='chr6' and chromStart =
31647790", you will get the following return:

 826     chr6    31647790        31649567        2389798 430695879
0.698777

Which means that the multiz17way score for the region chr6:31647790-31649567
(total 1778 bps) is 0.698777. But if you take this region into the browser,
the "17-Way Cons" track shown on the top as "Conservation" shows a lot of
variation (not a constant value of 0.698777) with peaks and dips.

Does the browser combine other information to compute the "Conservation"? If
I am interested in getting the conservation of a SNP rs909253, how can I get
it?

Thanks a lot!
