  • Alignment Cover for Simulated Illumina Reads

    Hello,

    I generated 100 M reads using maq’s simulate and simutrain commands. Once I align the reads against an assembly, I note that I get a much higher coverage alignment-wise than if I were to do with the same number of “real” reads. (The simulated reads and the real reads are of the same diploid strain.)

    Has anybody gotten similar results?

    Thx,
    BertieWooster

    Hi Bertie,

    In a simulation with reasonable mutation rates I have always managed to get somewhat better results than with real reads. Error modeling of your real data is always an approximation that will miss events that happen during a real run.
    There are other simulators you should try out. One that I like using is the dwgsim program in the DNAA package.

      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...
