    Hi Yi Huang,

    Thank you for writing to the GATK forum! I hope that we can help you sort this out.

    I appreciate that you have included the GATK version and the exact command you used. 

    To accurately identify the issue you are encountering, I'll need to see the entire program log/stack trace. Please include all error messages/exceptions so we may best diagnose the issue and determine the next steps.

    I look forward to hearing from you! If any other questions arise in the meantime, please do not hesitate to include them in your response.

    Hi Yi Huang,

    Thank you for providing your program log! I appreciate your patience while we worked on this.

    It appears that your code is throwing a BufferUnderflowException. This occurs when the program tries to query the index for one of your bam files. The error therefore implies a problem with your bam file indices. I also see a warning in your program log substantiating this:

    WARNING: BAM index file /home/huangyi/data/recal/W00139_2_recal.bai is older than BAM /home/huangyi/data/recal/W00139_2_recal.bam

    The above suggests that your bam index is out of date. You should re-index all your bam files using --samtoolsindex and try again.

    It appears that your VCF indices are also out of date by this line in your program log:

    IndexUtils - Index file /home/huangyi/data/somatic-b37_af-only-gnomad.raw.sites.vcf.idx is out of date (index older than input file). Use IndexFeatureFile to make a new index.

    You can use GATK’s IndexFeatureFile tool to re-index your VCFs.

    I hope this helps! Please let me know if you have had success after implementing these changes. Please do not hesitate to reach out if you have any other questions in the meantime.
