    help with ftp files from dbSNP

    Hi All,

    I have questions about some files that I donwloaded via ftp from dbSNP (ftp://ftp.ncbi.nlm.nih.gov/snp/datab.../nematode_6239)

    In both GtyFreqBySsPop.bcp.gz and GtyFreqBySsPop.bcp.gz files the IDs for genotypes are codified using 29, 39, 42, 43. I don't known to which genotypes correspond these numbers and I haven't found any explanation. And if this numbers actually refer to genotypes I think there should be more than 4 categories...

    Something similar happens with the file SNPAlleleFreq.bcp.gz. In this case there are 4 codes that correspond to alleles, my guess is that 2->G, 4->T, 6->A and 7->C. But again I couldn't find any explanation to confirm this.

    Any help will be very useful!

    See if the codes you are looking for are in the shared_data directory here: ftp://ftp.ncbi.nih.gov/snp/database/shared_data/

      Many thanks!

      I've found the answer in files Allele.bcp and UniGty.bcp

        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,...
