    Real SNPs discovered with samtools v0.1.7 disappear with v0.1.8

    Dear all,

    I used sanger sequencing to confirm some SNPs that I "discovered" with a GAII experiment using samtools v0.1.7. For a "bunch" of reasons, I generated a new pileup file using v0.1.8. The pileup looks like this for v0.1.7:

    How can the consensus quality and SNP quality go from 155 to 0 and 1?

    Thanks

    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,...
