Warning of gatk MarkDuplicatesSpark

Post author

I ran GATK MarkDuplicatesSpark on our cluster but got the following warnings. It looks the job finished and  the marked_duplicates.bam output was created. Due to the warnings, I wonder whether there might be concerns for  downstream BQSR analyses using the marked_duplicates.bam output.

Thank you!

    Hi Duan,

    Thanks for writing in. It sounds like you are running a GATK tool on your own cluster and not on Terra, is that correct? If so, a better venue for your question would be the GATK forum since this page is focused on issues related to the Terra platform. GATK support staff or a member of the community will be able to assist you.

    Best,

    Samantha
