      Hi,

      I dont have a GTF file, but I have a multifasta file with genes annotation. You know if can i use this file for mapping? how? I have converter this fasta file in GTF format? you know how?

      Thanks

        Hi!
        Wanted to bump this thread up a bit:
        What happens if you have pseudogenes? Will using tophat with a reference annotation (ex. the Gencode12 Comprehensive, which does not include pseudogenes), bias you against proper mapping of reads to these regions?

          I am also wondering about this and would be interested in hearing an answer.

            I would also be interested in a clear answer to this question.

            My worry is that by supplying tophat with an annotation file if it is then biased toward aligning to genes in the annotation instead of potentially novel genes.

              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
