    FPKM/TPM to raw read counts???????

    Hey guys,

    I am new to this. My question is if there is any way(s) to convert TPM into raw read counts? I currently have FPKM, TPM,effective length and length of the genes for my data set. If I understand correctly I could be able to multiply the FPKM values by the length of the gene, but that would be an incredible amount of manual work due to how the data I have is set up. So besides this way is it possible to convert the data I have into raw read counts? I intend to do other normalizations with the raw read counts because I am aware that TPM and FPKM are already normalized outputs.

    I apologize if this is unclear, though any advice would be great! If it helps I am currently using data from experiments I didn't conduct, so the FPKM, TPM, effective length of genes, and the length of the genes are all I have.

    Thank you!

    Please check the Bioconductor package tximport, which reverse-calculate read counts from FPKM/TPM, with two modes.

      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
