Percent of variant reads to make a heterozygous call

Hi,
I was wondering what is the min percent of variant reads GATK uses by default to make a heterozygous call and how to change this value if need be.
Thanks!

  • Thanks Geraldine.
    Is there a way I can set this threshold?

    Also, where can I get more details about how GATK exactly calls heterozygous allele?

    Thanks!

    Have a look at the presentations from recent workshops, a lot of the internal logic is explained there. For the various thresholds that can affect sensitivity, see the HaplotypeCaller tool doc (Guide>Tool Documentation) for a full list of options.
