    You know you can convert your V5 to a V3 chip?
    I did it and got MUCH better results on gedmatch.

    Thanks to this site : https://wilhelmhgenealogy.wordpress....match-classic/

    Give it a try.

Illumina, the company that makes the beadchip reader system is standardizing to a reduced SNP chip.

    Gencove stopped selling kits and accepting raw data, sucks

    Give it a try.
    Edit: I just re-did it and it seemed to fix the problem. I now have 186k SNP coverage after V3 conversion.
