I have a multigenome vcf file. Suppose the file has samples A to Z, but I want to extract the subset of samples B to G and extract a small vcf file. How can I make such subset  vcf file?
from https://samtools.github.io/bcftools/bcftools.html#view

    bcftools view -s samplelist

or

    bcftools view -S samplefile

would do the job. docs are your friends ;)
