    Gff3 files for H.pylori strains

    Hello,

    We are doing differential analysis (DE) in DeSeq for different H.pylori strains. We are not able to find the gff3 files for those H.pylori strains (98-10, 35A, 51, 52, F16, F30, F32, F57) to use in htseq-count.

    Perhaps you will know where I can download those gff3 files? The fasta files can be downloaded from NCBI, but not the gff3 ones.

    Thanks

    They are in NCBI, at least where I get bacterial genomes (which changed recently).

    In the subfolders of this directory: NCBI Helicobacter genomes the files that end in .gff.gz are gzip compressed gff3 files, here is the top of one:

    Code:
    ##gff-version 3
    #!gff-spec-version 1.21
    #!processor NCBI annotwriter
    #!genome-build ASM852v1
    #!genome-build-accession NCBI_Assembly:GCF_000008525.1
    ##sequence-region NC_000915.1 1 1667867
    ##species http://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=85962

        Sorry, I missed that you had a specific list of strains - I think you can find the genome accessions in this table so you know which folders to look at:

        This resource organizes information on genomes including sequences, maps, chromosomes, assemblies, and annotations.

          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
