    tophat 1.1.4 bam file

    When I convert the bam file from the output of tophat 1.1.4 to a sam file, it loses the strand specificity ie,, XS:A+/- at the end. This renders it unusable for cufflinks. The conversion I used is samtools view -h -o out.sam in.bam. Any suggestions?

    The latest version of cufflinks directly accepts the bam file produced by TopHat. you do not need to conver the bam file into sam file. I just did this a couple of days ago.

    $./cufflinks -G refGene.gtf accepted_hits.bam

    This works quite well

      I am having a similar problem with converted output .sam files. And when I input my .bam directly into cufflinks, I get the following within a second before the process terminates:

      Counting hits in map
      CIGAR op has zero length
      CIGAR op has zero length
      CIGAR op has zero length
      Total map density: 0.000000
      CIGAR op has zero length
      CIGAR op has zero length
      CIGAR op has zero length
      Do .bam files have a CIGAR string? Has anyone else encountered this problem?

        The part about this topic feels surprisingly grounded, and the details on the page is the bit that made me slow down. I’d keep <a href="https://kinpict.com/">ai family photo generator</a> bookmarked for later.

        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,...
