    rRNASelector error and Metaxa parameters

    Hello
    I'm having trouble to run rRNASelector on unix server through ssh.
    It starts, the dialog box opens on my screen, I choose the reads file (fasta), but then I get this error message:
    "Starting hmmsearch for forward using lib/16s_bact_for3.hmm
    Not right file format! -> Abort"

    My hmmer is ok, when I type hmmsearch -h it gives to me the help information.
    I've tried to run it choosing all possible paths for hmmsearch, but it just crashes. Besides this, the dialog box dynamics is so slow, I cant either change the length parameter...

    In parallel, I'm running Metaxa, and it seems to work well, but for my metagenomic dataset it is finding too few sequences. Is a poor richness dataset, in fact, but even though I was expecting more. My output for bacteria sequences is 61 reads of a total of 110504 sequences. This sequences are from Illumina paired end, merged through Flash, with a average combine of 81% and average length of 293

    The sequences used for rRNASelector are the same
    My goal is to run a diversity workflow in qiime.

    Thanks for every suggestion!!!

    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
