SGT and Genotype in strelka output

Question

[Shicheng Guo]

Hi All,

I try to use strelka for the first time to call somatic mutation for cancer samples. I meet two problems and hope to receive some help:

1. I find SGT=GG->GG and SGT=ref->het in INFO column, how to understand them?
2. FORMAT column don't have genotype, How to obtain genotypes for my samples?

Thanks.
