    Modifying bam file sequence names according to 2nd column

    Hi,

    I want to modify the sequence names in my bam file. They're supposed to be for paired end, but the names don't have /1 and /2 so I can't use software like bedtools bam2fastq. Anyway, I'd like to add /1 to the end of the name if the flag in the second column is 99 or 83 and then /2 if its 163 or 147. For instance

    Code:
    HSQ1008:141:D0CC8ACXX:3:2202:1520:59984 163     chr14   105899906       60      101M    =       105900110       305     CCTTTCCAGGAAAGGGAGTAGCGAGGCTGCTCACTTAGAGCCACGCACCTGGGGCTGACAGTGTGCCTGGCAGTACCTGTGTGGAAAGACAGTTACAGAGG   @C@DDFDDHHHHAHGBHG1AFHIGIJGIIGEIJIGIFE?BBGIIIIBHIEGHHHFFFEEEEEEDCCCCCDDCD?CACCDDDCBB@ACBC?CCDCCCACAC8   RG:Z:NA12877    XT:A:U  NM:i:0  SM:i:37 AM:i:37 X0:i:1  X1:i:0  XM:i:0  XO:i:0  XG:i:0  MD:Z:101
    should become

    Code:
    HSQ1008:141:D0CC8ACXX:3:2202:1520:59984/2 163     chr14   105899906       60      101M    =       105900110       305     CCTTTCCAGGAAAGGGAGTAGCGAGGCTGCTCACTTAGAGCCACGCACCTGGGGCTGACAGTGTGCCTGGCAGTACCTGTGTGGAAAGACAGTTACAGAGG   @C@DDFDDHHHHAHGBHG1AFHIGIJGIIGEIJIGIFE?BBGIIIIBHIEGHHHFFFEEEEEEDCCCCCDDCD?CACCDDDCBB@ACBC?CCDCCCACAC8   RG:Z:NA12877    XT:A:U  NM:i:0  SM:i:37 AM:i:37 X0:i:1  X1:i:0  XM:i:0  XO:i:0  XG:i:0  MD:Z:101
    How should I go about this? The bam file is also missing header information. Thanks!

    16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
    by SEQadmin2





    NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...

    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
