    How to extract those reads, that are not fully aligned in BLAST+?

    Hi there!

    Like the title says, How do i get those reads, that are not fully aligned in BLAST?
    Someone already tried it?

    What do you mean by fully aligned?

      If you aligned reads against a database, you will have to extract the identifiers of reads that did align to something first and then extract those reads from the original input file. There is no way to fully recover incompletely aligned query sequences from blast output (as far as I am aware).

        I've been doing something similar recently - mainly via awk command from a tabbed blast+ output and then using this file to filter an input sequence file.

        If you elaborate a little on what you are trying to do, I may be able to 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
