Should reference sequence surrounding homopolymer warning site show a long repetitive sequence?
I am using Variant Annotator to annotate my vcf. One of the annotations is Homopolymers run - I get several error messages like the one below regarding homopolymers. I have looked at the reference sequence for some of these positions and I don't see a long homopolymer run in the sequence. Should I be seeing a long homopolymers in the reference? Thanks for clarifying. I am using GATK 3.6.
