    What's wrong with my ChIP seq data?

    I perform H3K9me3 ChIP experiment and built the libarary acoording illumina's ChIP seq libarary protocol. The analysis of the data is as follows:

    raw read: 46891730
    map read: 42812364
    uniq read: 40442380
    used read:13409805
    map ratio: 91.30%
    uniq read: 86.25%
    used ratio:28.6%
    region: 253

    The used raed/used ratio/region is too low. I cannot figure out the problem, could anyone help me?? Thanks!

      More details, please. Where is your output coming from? What does "used ratio" refer to exactly?

          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,...
