    Motif enrichment in MEME - CentriMo

    Hello,
    I have a list of differentially epxressed gene for which I would like to see whether they are enriched over background (non DE genes) for a specific binding motif (looking at ±10kb TSS).
    I have used CentriMo for this but a) an not sure it's the best algoritham, and b) am unsure about the interpretation of the results.
    Because I have only queried one motif, my e-value = p-value. However I'm not sure how to interpret the Fisher E-value.
    Looking at the graph, there does not seem to be an enrichment.
    The E-value is 3e-75, but the fisher E-value is 1. Per the literature I would interpret there is no enrichment over background. Am I correct?
    Is there another more appropriate way to predict enrichment?
    Thanks!

      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

      New Genomics Technologies Take Aim at Long-Standing Limits
      by SEQadmin2


      Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

      We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
