    Illumina quality score encoding for galaxy grooming

    Hi all,

    To do fastq grooming on galaxy, I have to choose fastq input format, either Illumina 1.3-1.7 or Sanger, for reads done on HiSeq 2000 using GAPipeline vRTA1.10.36. A quality sample from the end of a 210 base read:
    6;95;6HHHHHHHHHHHHHHHHHHHHHHHHHHFHFFHHFFFHFFHHHFFFH>?AA>#@<?##

    If anyone can help me understand which input format to select, much abliged.

      It appears that the low quality rating "#" may indicate that this is Illumina 1.8, or "Sanger" in galaxy. However, RTA version 1.10.36 appears to be an old one. Also, nowhere do I have quality scores of I or J. So I'm confused, even after reading up.

        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
