    How to use mirna and mrna sequences in bowtie2?

    I have two files.

    1. An mrna file in which each line looks like -

    NR_030382 chr1:100154611-100178513 tattaggttggtgcaaaagtaattgtggtttttgcctgtaaaag

    2. An mrna file whose lines are like -

    >hsa-miR-576-3p MIMAT0004796
    AAGAUGUGGAAAAAUUGGAAUC

    Now if i am not wrong, the thing should be like this
    > mrna is from 3'utr, so i need to reverse it since mirna is also from 3'
    > now considering i am doing 6mer, i need to skip the first character from each sequence from mirna, then search the mrna file for the existence of its compliment

    How do I achieve this using bowtie2 ?

    Please consider the fact that I am just a regular computer programmer and this is my first time encountering anything related to bioinformatics. I think i'll be needing to do this for 7mer, 8mer and 7mer+a1 also.


    P.S - This was of no help, http://seqanswers.com/forums/showthread.php?t=72252

    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
