    SSPACE creates tandem duplications instead of merging

    Hi all,

    I'm using SSPACE v2.0 on a set of contigs assembled through Velvet, with parameters
    -x = 0
    -z = 0
    -k = 5
    -a = 0.7
    -n = 15
    -p = 0

    Reads library is a 400bp insert PE illumina 2x90bp.

    But when connecting overlapping contigs, the soft scaffolds them with a 'N' spacing instead of merging them. Such an issue should have been corrected in the current version of SSPACE ( see http://seqanswers.com/forums/showpos...3&postcount=97 ), but it does not work for me. Moreover, some overlaps are below 50 bp, i.e. the before-correction threshold.

    Perhaps it may help, but all cases I checked for show multiple link possibilities.

    Did it happened to anyone else with SSPACE v2.0 ?

    thanks,

    seb.

    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
