  • 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

          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...
