    Hi ,

    The GATK support team is focused on resolving questions about GATK tool-specific errors and abnormal results from the tools. For all other questions, such as this one, we are building a backlog to work through when we have the capacity.

    Please continue to post your questions because we will be mining them for improvements to documentation, resources, and tools.

    We cannot guarantee a reply, however, we ask other community members to help out if you know the answer.

    For context, check out our support policy.

    @lahl The resulting VCFs will not be exactly the same, but except in weird edge cases they should show the same variants.  We recommend the GVCF workflow for multi-sample germline calling.
