    Abyss assembly with Ion Torrent?

    Anyone have any experience using Abyss to assembly Ion Torrent data? I am getting some pretty awful results I think.

    I have 100X MiSeq coverage (2x150) and 100X Ion Torrent data (avg read length a little under 200). I did a kmer parameter sweep on both. My best MiSeq assemblies are getting me right around 200contigs, which is pretty awesome. Unfortunately Ion Torrent is up around 10,000.

    I think it is likely I am doing something wrong, but not sure what.

    MiSeq command structure:
    abyss-pe -j 8 k=43 name=k43 in='MiSeq_100X_1.clipped.fastq.gz MiSeq_100X_2.clipped.fastq.gz' > k43.log 2>&1

    Ion structure:
    abyss-pe -j 8 k=43 name=k43 se='Ion_PGM3_100X.clipped.fastq.gz' > k43.log 2>&1


    I'm going to be trying out some other assemblers, but just wondering what the f is going on here...

    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

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
