    Inquiry regarding input file for genome size estimation by Jellyfish

    Hi,

    Do anybody mind to share that what is the "best" or "suitable" input file for genome size estimation program such as Jellyfish?

    I still confuse should I used original raw sequencing read, pair-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc), or pair-end + single-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc)?

    I have try the above 3 different data as an input file for Jellyfish by using 17-mer.
    My data set is novel isolated bacteria.
    Thus I not too sure what is the exact genome size.

    The peak of 17-mer frequency (M) in reads is correlated with the real sequencing depth (N), read length (L), and kmer length (K), their relations can be expressed in a experienced formula: M = N * (L – K + 1) / L.

    All the above 3 different data set gives me different peak of 17-mer frequency.
    Thus it effect the calculation of genome size too.

    Thanks for any advice.

    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
