    How to do CASAVA alignment by using fastq files

    Hi, I am trying to make CASAVA1.8 work.

    The company give me the demultiplexing data (in fastq format), Can some one please let me know how to do the alignment with CASAVA1.8?

    I am very confused with all different folders created by CASAVA. can I run casava directly by only input the fastq files and the references? If not, may I know what kind of folder structure should I prepare for it able to process?

    Thanks a lot and happy new year!!!

    If you are getting data in "fastq" format (it is not clear if data is already de-multiplexed or does it need de-multiplexing) is there a specific reason you want to use CASAVA (eland) for alignments?

    It may be simple to use standard tools like bwa/bowtie/samtools to proceed with the downstream analysis.

    If you do want to run full CASAVA (alignments and down stream SNP-calling etc) then you would need access to the entire folder structure for the flowcell data. This process may be intimidating to learn, specially if this is a one time thing.

    You should be able to run just the alignments (with eland) standalone with right reference data files and sample sequence files. The command line options for doing that are described in the manual for CASAVA.

      Thanks GenoMax,

      the fastq files are demultiplexed, it should be ready to go.

      I am contacting the company to hand me the full "Unaligned" folder. Hopefully, I am able to run it tomorrow.

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

        New Genomics Technologies Take Aim at Long-Standing Limits
        by SEQadmin2


        Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

        We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
