SKATO hangs after going through several genes

Question

[@anna]

Hi there

I'm doing skato analysis with rvtest/2.1.0. My script:

rvtest --inVcf file.vcf.gz --pheno phenofile --out newfile --geneFile refFlat_hg19.txt --kernel skato

it runs for a while, but them skato seems to hang after a few genes

Does anyone knows what is happening and how I can solve it? thank you
