    Newbler assembly - excluding specific reads?

    Hi,

    I have sequenced genomic DNA from a eukaryote and have ran a newbler assembly of the sff file from the 454 lab. Some of the contigs are clearly belonging together, but are not assembled into one. This seems to be caused by a few reads that looks like artefacts from the genomic amplification. (These reads are split into two and the two halves match each end of the contig, like a circle.)

    I wonder if it is possible to run newbler and to specify that these reads (i have the names) should not be considered?

    Thanks!

    Jon

    Jon,

    Yes, you can exclude specific reads from the assembly. Create a text file with the read names you wish to exclude, one name per line, nothing else. When you run newbler use the parameter '-fe <filename>' where filename is the file described above.

      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
