    Fastx-barcode_splitter.pl

    Hello,

    I would like to use fastx_barcode_splitter.pl to creat individual read files for each samples, and have typed the following command in terminal. It has been separated each samples but also showed error. I also got one file that is containing unmatched.fq file which is 10.9 MB of the input file 19.6 MB.

    $ cat par.r1r2.fq | fastx_barcode_splitter.pl --bcfile barcodes.txt --bol --prefix "par." --suffix ".fq"
    Error: bad input file, expecting line with sequence name2



    Can anyone advice me how can I get rid of this error? Thank you.

    Is the error indicating a specific line in your sequence file? Perhaps you have a malformed sequence ID line.

      Hi GenoMax,

      Thanks for your reply. I have just decompresses *.gz back to *.fq file. I had three files namely, parent, progeny and strip. Progeny and strip worked perfectly fine, but error shows only in case of parent although I did same for all three files.

        Can you try to validate the fastq file (http://genome.sph.umich.edu/wiki/FastQValidator) to see if it spots the problem header line?

          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,...
