Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.
VariantAnnotator requirements for some annotations
I found that VariantAnnotator sometimes does not annotate some annotations that are requested.
A ) The Rank Sum Test annotations MQRankSum & BaseQRankSum
I was not able to identify the requirements that have to be met, so they are being calculated for a variant.
B ) InbreedingCoeff
This one seems to be connected to the number of total called alleles (AN).
For me there needed to be at least 10% alleles be called (19/186).
The doc for that says  "at least 10 founder samples". Maybe this has to be updated to 10%?
These are the ones I observed.
Can someone tell me more about that?
