    Bowtie2 Question

    Hello everyone,

    I am looping my code to run 24 alignments (--very-sensitive-local) for bacterial RNA-Seq.

    Here is my code:

    for i in ~/Desktop/RNASeq/trimmedreads/*_trimmed.fq.gz;
    do "bowtie2 --threads 36 --seed 1234 --fr --very-sensitive-local --no-discordant -t -x ~/Desktop/J53/ -1 $i -2 ${i/_001_trimmed.fq.gz/_002_trimmed.fq.gz}-S "${i%.fq}".sam;
    done

    There is no output in terminal, only the carrot. Top is a bit non-committal. I am worried it is caught up. I do not see bam directories being created in my current directory (j53). The index ran fine.

    Is it just taking forever or did I do something silly? This is my first time looping code.

    Of note, I am on a guacamole workstation and not on my local system. I have 36 threads available.

    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
