  • GATK variant calling for multiple exome

    Hi all,

    Currently, I am running Unified genotyper for variant calling for around 100 exomes. It's on the cluster and I found the remaining running time is aournd 3 weeks. Is there any way that I can do within few hours? It's my first time to analyze high-throughput data..

    Any advice would be appreciated

    That seems like a long time. Can you share some more details about what you are doing so we can see if there is opportunity for speeding it up? Certainly a generic answer would be to leverage a cloud service to use as much CPU power as you need but I would be interested in learning more about what you are trying to do...

      If you have a cluster you might want to look into the scatter/gather parallelism. Basically you do many GATK callings at once spread out around the cluster, with each job just doing a portion of the genomic intervals. Once all jobs are done you merge the results

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
