Dear Friends,

My vcf file has SNPs available for different population(Africa, America, Europe,East Asia and South Asia ). I want to extract the data for Europe and East Asia together . Kindly let me know the possible ways.

Thanks in Advance 
You can do this easily using vcftools, GATK tools, plinkseq etc. 

you first have to generate a text file with the list of samples that form the population of your choice, let's say "population_of_interest.txt"
Then,

    vcf-subset -e -c population_of_interest.txt input.vcf > output.vcf

or
 

    vcftools --vcf input.vcf --keep population_of_interest.txt  --recode > output.vcf
