    bfast bgeneratereads for paired ends

    Dear all,

    I was trying out the bgeneratereads utility just now, trying to obtain reads that mimic a paired-end experiment in colorspace with 50 and 25 bp read pairs.
    The specification file I generated looks like this:

    0 0 0 3 1 50 0 25 100

    however, the output is one single file in a format that resembles the solid2fastq output for paired end reads inputting both reads files.
    Also, I am not sure about what is meant by "read length" (field 6) vs. "paired end length" (field 8). I interpret it as "read length" = length of the first read of the pair and "paired end length" = length of the second read of the pair. Correct?

    Is it possible to somehow generate the two reads of each pair in separate files? (In order to proceed with the bfast match/bfast bwaaln combination?)

    Many thanks in advance for suggestions.

    cheers,
    Sophia

    to - in part - answer my own question, the specification file must look like this:

    0 0 0 3 1 50 1 25 100

    the field for paired end must be 1 (in that point the manual is wrong, saying "paired end" 0: true, 1: false - in fact it is the other way round).

    cheers,
    Sophia

      This utility is not supported within BFAST. Try the "dwgsim" tool within DNAA (http://dnaa.sf.net), which should be more friendly.

        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, detection...

        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
