  • 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!

    Are you using newest version of Cufflink. I beleive this has been taken care in the newest version.

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

      Thanks a lot!

        Current Approaches to Protein Sequencing
        by seqadmin


        Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

        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...
