    Tophat2: Error running bowtie:

    I am trying to map illumina paired-end datasets using tophat2. Everything seems to work fine but I suddenly get an errormessage concerning bowtie:

    Please look at the tophat.log file. Does it give you an error?

        Tophat2 error at the end

        Hi dfhdfh:

        I am newer in NGS analysis. I recently used tophat2 to align illumina PE RNA-seq. At the end of running, there is an error, I really don't know how to solve this problem. Please help, thanks.
        I am using Oracle VM VirtualBox linux system.

        calgary@ChanLab:~/BT2_HOME$ tophat2 -o 81MAGABXX_5PE ./indexes/hg19 /media/sf_F_DRIVE/finished/81MAGABXX_5_R1.fastq /media/sf_F_DRIVE/finished/81MAGABXX_5_R2.fastq

          Ouch. It is painful to get that error after running the analysis for 2 days!

          So it did not make the "81MAGABXX_5PE" directory?

            can you please tell what is your system configuration and which genome are you using

              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,...
