Selecting sites from VCF which have an alt AD > 10 I have high-depth variant calling created using the HaplotypeCaller with --output_mode EMIT_ALL_SITES I'm interested in finding all sites (regardless of genotype call heterozygous or homozygous) where at least one of the alternative alleles have an AD value (Allelic Depth) greater than 10, I.e. are supported by more than 10 reads. Also ideally I want back more than just the first alternative allele.  Note that I don't want back lines of VCF were we only see an AD count for the ref allele only.
So in the example VCF snippet below I'm wanting to select lines: 6,7,8,12,13 and 14, which have GT:AD values 1/1:1,988:989 0/1:116,92 0/1:220,234 0/1:62,611 1/1:0,109 respectively.

I'd initially considered using GATK's SelectVariants but I'm not sure JEXL has the ability to select out what I want specifically other than a blanket AD &gt; 10 which will give me both ref and alt alleles with AD &gt; 10.  Perhaps there is a bioawk solution or something more elaborate with coreutils which could successfully return sites with an alt AD count &gt; 10?
using vcfilterjs

and the following script:

function accept(vc)
    {
    var i,j;
    for(i=0;i&lt; vc.getNSamples();++i)
        {
        var genotype = vc.getGenotype(i);
        if(!genotype.hasAD()) continue;
        var ad = genotype.getAD();
        /* loop over AD starting from '1' =  first ALT */
        for(j=1  ;j&lt; ad.length ;++j)
            {
            if(ad[j]&gt;10) return true;
            }
        }
    return false;
    }
accept(variant);


usage:

java -jar dist/vcffilterjs.jar -f script.js Test.vcf
