    How to use ARB nifH database(Zehr et. al) for taxonomic assignment

    Hello members,
    I am new in metagenomics data analysis. Currently I am working on a nifH amplicon data. I have done quality filtering, merging and construction of ASV's using DADA2 denoising method in QIIME2. Now I have to do taxonomic assignment to the ASV's. A nifH gene sequence database is available by jzehr lab which is in .arb format.

    I couldn't find out a way as to how can I use this database in .arb format to assign taxonomy.
    Is there any specific tool or method to do this?

    Is the sequence as well as its taxonomy data available in the arb database?
    How databases in .arb format are viewed or used for such kind of data analysis?

    Can anyone please guide me in this regards?

    Thanks in advance.

    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
