    Search specific blast database regions

    Hi there,

    I am using blastn in command line. I have a genome and created a blast database out of it with makeblastdb
    During the pipeline I am developing I need to blast some sequence versus specific chromosomes of the genome and not the entire genome. At the moment I use the command

    blastn -query queryFile -db genomeDatabase -outfmt 6

    Let's say that in the genomeDatabase file I have chr1, chr2, chr3 and so on. What can I add to my command to search my sequence versus just chr1 or chr2 and so on?
    thanks for your help!

      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      ...
