    cuffcompare output combined.gtf question

    Hi there,

    I am wondering how to understand the second column of the combined.gtf? It's supposed to be source: the program that generated this feature. I look at my combined.gtf file and see there are several sources: "protein_coding", "pseudogene", "processed_transcript" and Cufflinks (and more). I can understand the first three sources, how Cufflinks relates to them? Does it means if the source is Cufflinks, the transcript is novel? But then I look a few of them having a Cufflinks as source, they are known genes. Some of them are protein coding genes. Why are their source not "protein_coding"?

    Thanks you for your help.

      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      ...
