    Will this stand up in genome curation court?

    The sequence in question is an approximately 2.2 Mb RS1 SMRT cell=4 Neisseria genome that i would like to seek your guidance on.
    I used my assembly of this organism (which is the first single contig sequence of its strain's kind) as a reference for SNP calling using the breseq pipeline.

    1) Every one of my results has an identical "unassigned missing coverage evidence" section. This consists of 2 sections at either end of the genome.
    2) A graph displaying coverage over the course of the genome shows an average of 500x but two small negative spikes of quality at either end of the genome
    3) I annotated my assembly using prokka and visualised the .gbk on artemis.
    These two regions share 100% complemented homology
    i.e. with numbers representing put. ORFS
    1,2,3,4-high coverage genome-4,3,2,1
    in 13000/16000 base pairs (these are annotated with the same hypothetical proteins and tbpB (transferrin binding protein) variants

    Based off this body of evidence, am i justified in trimming this sequence off my final assembly which i will publish?

    P.s.
    I wanted to give the community all of my annotation files as well, is there a resource to this via refseq or should I privately host them somewhere?

    Sounds like the assembly needs 'circularizing' https://github.com/PacificBioscience...g-and-trimming

      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
