    samtools view -l/-r options

    Hi everyone!
    Is it possible to retrieve mapping results of several specific reads from bam or sam files by referring to the read names?

    I tested the following options and couldn't get it working:

    -l STR only output reads in library STR [null]
    -r STR only output reads in read group STR [null]
    -R FILE list of read groups to be outputted [null]

    I have a txt file that includes names of several candidate reads, and I would like to extract the mapping info of the reads from a bam/sam file.
    Could some one please provide an example script on how to do that?

    Thank you!

    Cheers.

    Check out the fgrep command with the -f parameter.

    samtools view file.bam | fgrep -f candidates.txt

    Play around with a small examples to figure out how to use fgrep.

      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
