    how to use medpolish in R/Bioconductor

    I'm trying to perform median polish on my RMA-normalized microarray data.

    The function medpolish, which seem be able to perform median polish, outputs a matrix of factors. Am I supposedly use the input matrix/table subtract this output table/matrix? And the subtracted result would be the actual median polished result?

      wonder if this is the correct forum to ask microarray questions

      anyway i suggest to start with a bioconductor functions such as colSummarizeMedianpolish in the preprocessCore package that is more intuitive to use.

          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          ...
