    A new fruitfly genome de novo sequencing

    I have no experience in de novo genome sequencing, and i have a now project:

    A fruitfly genome de novo sequencing, and i want to use the Allpaths pipeline to assembly the genome, and want to use 180bp + 3K insert size illumina Hiseq 2000 sequencing, each libray squence one lane (>30Gb),

    Dose this work?

    Can anybody give me something advice?

    Thanks!

    It's a good start, but only just fulfilling the minimum ALLPATHS_LG requirements. Adding more libraries of larger jump sizes might make for a better assembly. I just hope you have enough compute capacity/memory/disk space...

      By Hiseq 2000 sequencing and 30Gb data, should be 200x coverage for fruitfly, it's supposed enough for genome assembly. Also, you can use other pipeline to analysis data in the same time, like SOAPdenovo etc.

        You certainly have enough data in terms of paired end coverage, but that doesn't really ensure it can be assembled.

        I have no idea how complex a fruitfly genome is in terms of repeats and near-repeats (tandem or otherwise), but it would need to pretty simple to get away with just one size of mate-pair data.

        Then again, perhaps it is simple - maybe try an illumina read simulator using the drosophila genome, and see how well you can re-assemble it from simulated datasets.

          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
