    Extract reads contains repeats

    I MiSeqed heterogeneous templates amplified via rolling cycle amplification (RCA) by a specific 6-nt primer. PE reads were merged into single ones around 500 nt. As a consequence of RCA, some of them consist of 100-200 nt repeats from short-size templates. Is anyone aware of tools that can process, extract, and consensus these kinds of reads? Many thanks.

    You could take an example sequence and then use "bbduk.sh" from BBMap suite in filter mode to extract reads containing that sequence with "literal=sequence_you_want" option. Guide to use bbduk is here.

      I believe that is what I want. Thanks!

        GenoMax: Can I extract/separate reads with 0, 1, or 2 motifs (the motif is the same)? Could BB scripts do this job?

          Possibly. You will have to play with parameters for bbduk.sh. "0" should be easy to get.

              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,...
