Hi, Dear UCSC Genome Browser group,
I downloaded the table "snp132common" from the track "Common SNPs(132)".
In the filter, I choose "valid does include by-hapmap" only.
Here is the statistics shown by the browser. The number of hapmap SNPs
is only half of what hapmap homepage provides (~ 4.2M).
Could you please explain why? Thanks
Xiang
