Off topic:PCA plot using exome-seq data VCF and 1000Genomes data

Question

[VasGene]

Dear all,

I would like to check the ancestry of several individuals for which I have individual VCF files. The VCF files are based on b37.

I would like to run principal component analysis to confirm overlap with individuals of Caucasian ancestry included in 1000Genomes and plot my results. Any idea how I could do this?

Thanks very much.
