    Bedtools Intersection files

    Hello,

    I have a Splice Junction file in the tab delimited format and it looks like this:

    Hello,



    I have a tab delimited format Splice Junction file and the file looks something like this:

    Code:
    chr1    11212    12009    1    1    0    0    2    48
    chr1    11672    12009    1    1    0    0    1    31
    chr1    11845    12009    1    1    0    0    1    28
    chr1    12228    12612    1    1    1    0    1    32
    chr1    12722    13220    1    1    1    0    3    9
    chr1    14830    14969    2    2    1    0    218    50
    chr1    15039    15795    2    2    1    0    98    50
    chr1    15948    16606    2    2    1    1    10    48
    chr1    16766    16857    2    2    1    0    24    44
    chr1    16766    16875    2    2    0    0    2    36
    The details are:

    Column 1: chromosome
    Column 2: first base of the intron (1-based)
    Column 3: last base of the intron (1-based)
    Column 4: strand
    Column 5: intron motif: 0: non-canonical; 1: GT/AG, 2: CT/AC, 3: GC/AG, 4: CT/GC, 5: AT/AC, 6: GT/AT
    Column 6: 0: unannotated, 1: annotated (only if splice junctions database is used)
    Column 7: number of uniquely mapping reads crossing the junction
    Column 8: number of multi-mapping reads crossing the junction
    Column 9: maximum spliced alignment overhang

    I want to create a intersection file using bedtools to find reads that have annotated junctions, unqiuely mapped reads and number of multi mapper reads equal to or greater than 10.

    I have not used Bedtools before so can I get some pointers on which command to use and how to input these parameters?

    Thanks!

      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
