  • Extract reads according to selected indexes (MiSeq))

    Hi all!
    I'm a new in bioinformatics. I have some questions about MiSeq data analysis. I have demultiplex data namely index fastq files, R1 and R2 fastq files. I need extract paired-reads according to selected indexes. Why? Because there are several different degenerate sequences of indexes and I would like to extract and analysis them separately. How is it possible to do? May be somewhere is there scripts ????
    I'll really thankful for any help!

    Indexed reads generated with the Illumina MiSeq can be demultiplexed with Illumina CASAVA. There is an option is CASAVA to change the maximum number of mismatches to support these degenerate sequences.


    See these scripts for an example on how to use configureBclToFastq.pl from CASAVA.

      Seb, thanks a lot for your replay. I've installed CASAVA it works pretty good!

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
