    Hi Yangyxt

    Thank you for reporting this issue. This looks like a bug and we have created a github issue here. You can use that link to track the progress that the team makes to solve the issue.

    A workaround that you can use  in the meantime is to exclude the StrandBias annotation. You can do that using this argument: "--annotations-to-exclude StrandBiasBySample"

    Dear Gandham,

    Thank you for your response! Can I ask what effect will I get to exclude this StrandBiasBySample annotation?

    Hi Yangyxt, I just spoke with my team about that workaround. It is leaving out the StrandBias annotation from your output, which may not be the best option.

    A better option would be to use an older version of CombineGVCFs before this bug existed. I would try 4.1.4.1 and see if that works.

    Yangyxt we are looking at recreating this issue. Are there any 3 VCFs that replicate this problem? Please upload those 3 as a bug report as well as a link to the reference you are using. Let me know when you have done this and what you have named the folder.

    Yangyxt do you have an update about sending those files so we can check the issue on our end?

    Could you also try this command with GATK 4.1.6.0 and see if the issue persists? We are working to find the specific issue.
