  • context-dependent sequence error

    Have you ever read such report? seems I found some sequence error hotspots.

  • #2
    Error "hotspots" exist for every technology I've looked at.

    E.g.:
    • older Sanger ABIs (370 and 373) had the "AG-problem".
    • 454 has the homopolymer problem. To be honest, Sanger sequencing and Solexa also have it ... but much less pronounced.
    • for the Solexa projects I've analysed, I've seen strong bias after GGC.G, see also http://seqanswers.com/forums/showthread.php?t=1353


    SOLiD I have no idea, I never analysed that data.

    Regards,
    B.

      Hey Bach, Thanks for your response, we plan to go deep into the sequence error, hope can get more general ideas.

      now we get too much AC misidentification, and seems they cluster into several positions.

        I guess that is due to A and C intensities being so similar.. and phasing makes it worse with increasing cycle-number

          Recent Advances in Sequencing Analysis Tools
          by seqadmin


          The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

          Essential Discoveries and Tools in Epitranscriptomics
          by seqadmin




          The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
