    CuffDiff error question, please help!

    I am running CuffDiff, but have response as following:
    > Processing Locus chr16:2016958-2028856 [******** ] 33%Error: sqrt(det(cov)) == 0, 0.000000 after rounding.
    Error: sqrt(det(cov)) == 0, 0.000000 after rounding.

    something wrong for it?

    For sample A and B, first I ran TopHat to produce A.bam and B.bam; 2) I run Cufflink to get A.gtf and B.gtf; 3) I then ran CuffCompare A.gtf B.gtf to get the A+B(combined).gtf; 4) last I ran CuffDiff A+B.gtf A.bam B.bam, and it responses the error information as above; is it right thing or not? I have waited for a few hours to the see the final list... Thanks!

      what kind of errors are these? Will interfere the interpretation of the results?

      Thanks a lot!

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

        New Genomics Technologies Take Aim at Long-Standing Limits
        by SEQadmin2


        Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

        We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
