    ^ I have not but this was something that was just suggested to me and I might give it a try. For generating the matrix file, how many tiles do you think is adequate? And do you do all cycles or can I shorten that as well?

      I usually pick 10-20 tiles and then run for 25 cycles. I try to avoid picking tiles from the flowcell edges as they're more prone to have problems. It runs pretty fast and gives you a Bustard.xml that you can check it to see if the pass filter/etc looks reasonable before doing a full pipeline.

        Does adding the PhiX spike-in to each sample have the same effect as adding an ERCC control? Ambion offers this ERCC control to help with accurately quantify transcript levels, but I'm not sure if I need to invest in this addition or not... Any thoughts?
        Thanks

          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
