    Tophat

    Could you please tell me how I can find out how many reads have been mapped to the genome after running Tophat for pair end RNA seq data?

    Thanks

    There are quite a few ways depending on what software you have.

    I would recommend using either bamtools stats or Picard's CollectRnaSeqMetrics to get some more information.

      On the accepted_hits.bam, run Picrads, SortSam.jar, BuildbamIndex.jar, ReorderSam.jar and CollectAlignmentMetrics.jar in order. The resultant metrics file has alignment stats.

        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,...

        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
