  • 1000 genomes human reference

    Hello,

    I'm using hg19.

    As you may know when you perform variant calling, reference variation allele may be biased due to the human reference we use (it's very uncommon but it does happen).

    I would try a different human reference, I would like to know if there's any with 1000 genomes data. And try doing some variant callings and then compare results.

    I've found the following link, but I'm not sure if this is a reference from 1000 genomes data:

    ftp://ftp-trace.ncbi.nih.gov/1000gen...k_v37.fasta.gz

    If someone could bring me some light on this issue.

    Thank you.

    Best regards.

    If there's no human reference coming from 1000 genomes data, is there any other alternatives to standard hg19?

      Hi gmarco,

      Yes, that is the reference genome if you are using the variants from phase 1.

      1000genomes.org is your first and best source for all of the information you’re looking for. From general topics to more of what you would expect to find here, 1000genomes.org has it all. We hope you find what you are searching for!

        http://www.1000genomes.org/faq/which...bly-do-you-use
        Then I guess 1000genomes reference for phase 2 is:

        ftp://ftp.1000genomes.ebi.ac.uk/vol1...e/hs37d5.fa.gz

        Maybe I miss explained myself. I want to try to map my data with a human reference based on 1000 genomes project and obviously different from hg19.

        I don't know if that 1000 genomes reference available for download is the one they used in the project, or if it was generated by 1000 genomes project.

          Strategies for Sequencing Challenging Samples
          by seqadmin


          Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
