Annotate ethnic or ancestry in specific region by using VCF file from whole exome sequencing

Question

[sonsunjirachote]

Dear community

I recently have a project to identify ancestry of patient. I have tried EthSEQ R package to annotate the ethnic of my sample vcf and work perfectly with expected output. However,I have notice that the output is superpopulation code from 1000 genome database such as AFR, SAS or EAS but I need more specific information like country or region such as Arab,Indian or chinese. Could it possible to get this information or any suggestion to identify the variant ethinic more specific.

Thanks in advance

JK.
