    I found a big discrepancy between the two also.

    AncestryDNA gave me:
    68% Europe West
    19% Ireland/Scotland/Wales
    8% Great Britain
    4% Iberian Peninsula
    1% Europe South

    My Heritage was:

    72.6% Irish/Scottish/Welsh
    25% English
    1.5% North and West Europe
    0.9% Italian

    For Southern Europeans too. My Dad is half Italian and MyHeritage gives him only 23.7% Italian, and 46% Greek. Even if you combine them, it's nearly 70% - way, way more than his Southern Europe should be. In comparison, AncestryDNA gives him 44% Europe South, and 23andMe gave him about 53% in Southern Europe combined.

    So maybe it depends on when you transferred the data and the model they were using at the time. It is perplexing (I was rather excited at the prospect of Scandinavian ancestry)
    I uploaded my raw data there in May and never received an update (that I know of) in July. Is there a way to tell whether my results are Version 9.0 or 9.5?

    My results on Gedmatch k3 DNA results were very different from my 23andme results.... 23 and me said I'm mostly British and Irish with a hint of northwestern European and Scandinavian. But my Gedmatch k3 DNA results on the pie chart says 3.34 eastern eurasian and 96.66 western eurasian and SSA i dont know what that means... then when i look at the spreadsheet it shows
    1.82 % Albanian
    2.77% Armenian
    2.9% Estonian
    3.1% southern French
    3.4% Abkhasian
    2.3% British
    2.24% Belarusian
    0.26% ukrainian
    1.65% Georgian
    0.56% Norwegian
    1.0% Croatian.
    11% Russian
    4.4% mongolian

    SSA means Sub-Saharan African. And I wouldn't worry about the oracles on the K3 -- those give weird results for just about everybody. (Which is probably because it only has 3 incredibly broad categories of ancestry that it's looking at.)
    Ancestry paper trail tally: 21.1% Colonial American (British Isles, German, Dutch, Swiss, French), 14.1% not traced past 19th Century United States (MD, NJ, NY, PA, VA), 7.8% Canadian (Ontario & Quebec), 40.6% German, 15.6% Czech, 0.8% British & Irish

    Yes -- to follow up on what Pox Voldius said, the Gedmatch calculations work differently than companies like 23andMe.

    23andMe tries to identify the counties that your ancestors likely were from in genealogical time. For example, if you are American, the countries they would have come here from.

    The various Gedmatch calculators identify different components and then use those components (with the oracles) to give some possible ancestry estimates that fit them. If you look at the related spreadsheet you can see that even non-mixed people from a single country will get a variety of components. Also, some Gedmatch calculators work better than others for different people. Something like Gedrosia K3 is supposed to be suited to people of Asian ancestry, so might not be a great fit. See https://iowadnaproject.wordpress.com...mixture-tools/

    It also seems to only do Oracle 4, which doesn't work as well if your ancestry doesn't fit into 25% chunks.

    Mine says:

    1 W_Eurasian 95.74%
    2 E_Eurasian 4.03%
    3 SSA 0.23%

    As you can see, those are super broad categories, so don't really let it distinguish well between people who are mostly Western European (whether it actually works well for Asians, dunno, although I am a bit skeptical given the categories).

    For me, the results are way off, quite a bit more Eastern Europe than the reality is (the Eurogenes tests work a lot better for me).

    Using 1 population approximation:
    1 Ukrainian @ 0.000000
    2 Lithuanian @ 0.654060
    3 Hungarian @ 0.769553
    4 Georgian @ 1.090258
    5 Belarusian @ 1.127463
    6 Bulgarian @ 1.298983
    7 Norwegian @ 1.701788
    8 Estonian @ 1.786995
    9 Czech @ 2.050286
    10 Croatian @ 2.130982

    Also, those aren't percentages. They show how close you are to the particular population, in theory. Although as I said it's way, way off for me.

    I also got rather diverging results. Perhaps not dramatic in the big picture but certainly quite different in detail.

    AncestryDNA had me at

    35% Scandinavian
    25% Europe West
    25% Europe East
    8% Great Britain

    but at least traced all of those back to the region "Germany, Netherlands & Belgium"

    MyHeritage had me at

    67 % English
    21% Balkans
    8% Finnish
    4% Scandinavian

    Now, in terms of traced genealogy a few generations back, I am 100% ethnic German, paternally from Northern Germany and maternally from Central Germany. I come from an "Old World" family in the sense that no-one, prior to myself, in my own lineage had emigrated from Germany. There is no known English ancestry, Finnish ancestry, Scandinavian ancestry or Balkans ancestry for that matter in my family.

    I therefore assume that the computers see a fairly typical German mix and recognize that a lot of it is highly similar to reference populations in Scandinavia and Britain while some of it is more similar to assorted Eastern European reference populations. The main difference seems to be the different labels they slap on those findings. It's curious though that MyHeritage has such a difficult time finding the label "German" given that Gedmatch Oracles almost exclusively show Germans as closest matching populations. I get that Northern Germany and England are pretty close genetically, and perhaps there's a significant gap between my genes and further Southern and Western German references, but if a free project can narrow it down..a commercial service should definitely do as well.

    Finnish also strikes me as rather bizarre..as Finland is generally viewed as a somewhat isolated place genetically and there's no known substantial migration pattern between Germany and Finland in the last several hundred of years.
