  • Non-random Illumina sequencing error?

    We have observed a couple of relatively frequent (1:4) SNPs in what is supposed to be a clonal culture. The simplest explanation is that it's not a clonal culture, but has anyone ever observed what seem to be non-random sequencing errors on an Illumina platform? In other words, context-dependent errors?

    Yes...

    What platform/chemistry are you using? Also, have you tried this? It should greatly reduce the quality scores of bases that are involved with some sort of nonrandom error-inducing motif.

      It might also be interesting to report the problematic sequences, given that specific sequences are know to give non random errors.
      For example, sequencing errors have been report with inverted repeats and GGC sequences on some Illumina platforms.

        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...
