    Roche 454 Amplicon Variant Analysis Help

    I need a bit of help with my attempts at using Amplicon Variant Analysis (AVA).

    I have a consistent problem when attempting a new analysis. I have correct references and annotation files imported. I have good data files (sff). When I attempt to build the associations everything appears correct when I compare what I set up to a previous successful analysis, but when I attempt to compute it, it says there is no active data to trim.

    It acts as if there is no data in the associations, but it is obvious I have active sff files associated. When others in my lab attempt the same analysis using my same imported files and data, it will work. I try to copy it exactly, but it doesn't work for me.

    In addition, I've tried to add new data to previous successful analysis files, but the software doesn't recognize the additional data and will only ever rerun the previous analysis.

    There must be some minutia that I'm missing while building the associations and attempting the analysis. Any idea what my problem is? I can't even begin to guess what's up, I'm not missing any major steps. Is it really that sensitive to the order I do things?

    Did you check a box "Active". In project click "Read Data" tab, you will find menus "name" "annotation" "group" and "active". Check the box and try it.

      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
