    Bam output from SMRT Portal

    Hi,
    I don't know what's going on; after running RS_Resequencing.1 from SMART Portal (because the protocol BAM_Resequencing_Beta.1 did't work), I get a mapping report of ca. 90K reads mapped. But when I select to download the aligned reads BAM file (down in Resequencing panel) I get a lousy file:

    Code:
    samtools flagstat pacbio.bam
    418 in total
    0 QC failure
    0 duplicates
    418 mapped (100.00%)
    I guess there is something I missed, but what?

    PS. the H5 aligned reads file looks bigger, at least in size.
    PS2. I set Max. divergence 30%

    Thanks

    What version and patch level is your SMRT Analysis install?
    Do you have access to the job directory? Can you run the same test without downloading through SMRT Portal, and use the SMRT Analysis version of samtools?

      smrtanalysis_2.3.0.140936.run with smrtanalysis-patch_2.3.0.140936.p3.run.
      Samtools flagstat from the file aligned_reads.bam in the job directory has the same outcome.
      Sorry, what's the "SMRT Analysis version of samtools"?
      Thanks

        SMRT Analysis comes with it's own version of samtools, `which samtools` should point to the SMRT Analysis directory. To make sure you are using it, `source <SMRT Analysis>/etc/setup.sh`
        I see very different output:
        Code:
        samtools flagstat aligned_reads.bam
        199382 + 0 in total (QC-passed reads + QC-failed reads)
        0 + 0 duplicates
        199382 + 0 mapped (100.00%:nan%)
        0 + 0 paired in sequencing
        0 + 0 read1
        0 + 0 read2
        0 + 0 properly paired (nan%:nan%)
        0 + 0 with itself and mate mapped
        0 + 0 singletons (nan%:nan%)
        0 + 0 with mate mapped to a different chr
        0 + 0 with mate mapped to a different chr (mapQ>=5)

          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, detection...

          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
