Different query results

[Li-Yuan Hung]

Today I used two strategies to query the allele frequency (AF):

(1) Using [Query Kaviar] on the website http://db.systemsbiology.net/kaviar/

(2) Searching the downloaded vcf file http://db.systemsbiology.net/kaviar/Kaviar.downloads.html

When I compared the two sets of AF results, I noticed significant differences in most variants.

Here are some examples:

RSID	WebsiteQuery_AF	DownloadedVCF_AF
rs540	0.566836	0.0961454
rs548	0.11593	0.0000064,0.0196651
rs557	0.209834	0.0355875
rs558	0.253469	0.0429892
rs568	0.242247	0.0410858

May I know which AF result is the correct one? Thanks!
