    HI Jenifer

    Seems like there is an issue with your input vcf.

    1. Can you please confirm that your input vcf is infact gzipped and not truncatted? Maybe try unzipping and gzipping your input vcf again.
    2. Can you please run ValidateVariants to ensure that the input vcf is not malformed?
