    HiSeq 2000 - fastq - read naming - Tiles

    Hi all,

    Does anyone have a sample of a fastq file generated by the HiSeq 2000 sequencer (with only a few reads) ?

    Our team will be analyzing HiSeq 2000 data soon but we only have GAIIx data in our hands at the moment.

    Concerning GAIIx sequencers, we know that a lane is made of 120 tiles organized in a 60*2 fashion. These tiles represent locations where the machine take pictures. Knowing how tiles are organized in the lane allows one to analyze the spatial distribution of the clusters within the lane, biaises, any problems, etc...In the fastq files generated by GAIIx, the identifier of the read contains information on the lane, the tile and coords within the tile. Is there something equivalent for Hiseq sequencers ? I was not able to link on the web HiSeq 2000 sequencer and the concept of tile (maybe because the optic system changed).

    Does someone have any clue on this point ?
    Is it possible to physically map reads on the lane for Hiseq similarly to what we can do for GAIIx sequencers ?

    regards,

    tony

    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, detection...

    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
