    paired-end question

    Hi,

    I am trying to figure out Solexa paired end read output. Can someone please tell me if my toy example is correct?

    1) One end of DNA is bound to substrate (##). Free end is sequenced in 5'-->3' direction.


    5'
    ------>
    GCCCxxxxxxATTT # ==> GCCC
    CGGGxxxxxxTAAA#




    2) Opposite end of DNA bound to substrate (##). Free end of *complementary* strand sequenced in 5'-->3' direction.


    5'
    ------>
    AAATxxxxxxGGGC# ==> AAAT
    TTTAxxxxxxCCCG #


    So the final output of the Solexa machine would be the pair (GCCC, AAAT) and then a program such as maq would worry about the details of orientation/taking complements. (Or would the pair be (GCCC, TTTA)?)

    Thanks,
    hja

    For future reference, if you use the [ code ] .... [ /code ] tags it will use a fixed width font and be easier to align!

      16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
      by SEQadmin2




      NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

      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
