    how to align the contigs to the reference genome

    Hi all,

    I am trying to do the de-novo assembly for my RNAseq dataset. First, I want to compare the accuracy of different assembly tools.

    Hence, I select one RNAseq data which already a reference genome.

    And we have assembly many different transcripts/contigs.

    Now, I want to check where these contigs coming from the chromosome and how many contigs can be aligned to the chromosome.

    For this questions, can anyone give me some suggestions about which tools is applicable?
    Because the length for the contigs/transcipts is much longer than the original reads, how any mismatch I should set for the alignment?

    Thanks!

    MUMmer is the a definite tool for mapping assemblies onto references.

      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
