    In my case only deleting majority of samples can improve results. Even reducing populations to 3 with all samples cant

    Here is what I get with all samples on 0.25x

     
    Target: Cyryl_scaled
    Distance: 1.6759% / 0.01675899 | ADC: 0.25x RC
    49.0 Ukrainian
    21.8 Bosnian
    19.8 Sorb_Niederlausitz
    5.8 Mountain_Jew
    2.4 Mari
    1.2 German_East



    Only Polish, Balkan, Western Asian samples

     

    Target: Cyryl_scaled
    Distance: 1.8847% / 0.01884716
    70.2 Polish_Southeast
    15.8 Polish_West
    7.2 Greek_Trabzon
    6.8 Albanian


    Relatively good results in 2 run, but still only regionally haha, even if you are 1/8 something different from majority ancestry, you will have problems with accurate modelling, but I am sure G25 works perfect for completely unmixed people

    What do you get for your distances?

    Single is like a oracle. It will break down the components to the possible best fit.
    That does not mean it shows your real ancestry. But possible combinations rather.


    I take myself as an example,
    Below is the modern average populations with closest distance to myself:



    Distance to: Nino_scaled
     
    0.03392686 Afrikaner
    0.03546667 Dutch
    0.03672958 German
    0.03711056 French_Brittany
    0.03760816 Welsh
    0.03796138 Norwegian

    0.04093370 French_Nord
    0.04134256 Orcadian
    0.04136284 Irish
    0.04159342 English_Cornwall
    0.04178019 Swedish
    0.04194514 Shetlandic
    0.04313361 French_Alsace
    0.04353401 French_Paris
    0.04412031 Icelandic
    0.04566962 Swiss_German
    0.04663781 French_Seine-Maritime
    0.04808226 Hungarian
    0.04935593 Czech


    As you see. I am most close to Afrikander ( White South Afrikans ) and dutch, Germans etc.
    This does not mean I am Dutch or Afrikander. I am not. But i have similar levels of ancient components as these peoples.

    If you are not of mixed European ancestry. These calculators will work better most of the times.



    Here is my "Single" :



    Shows Scandinavian admixture (I am around 50-65% Swedish)
    and also Spanish + Swiss French (Possible proxy for my Italian ancestry).

    Cossack_Kuban (I have no eastern european ancestry, this component is somewhat shown often in Swedes. But it is not real).

    Nganssan + Itelmen = Show my Siberian admixture from my Saami side.


    If you choose "REDUCE" you can set the populations from 3 to 7.

    Here is my results when choosing 3:

    One more question if you don’t mind, I don’t want to create a new thread every time I hope to understand something haha. But like I said previously my Eastern Europe does not show up in the single tool but if I alter the Add Dist Col to different numbers it starts to appear. The distance doesn’t change too much either, I don’t get anything below 2 and with Add Dist Col altered it still ranges between 2 to 4

    Please send me a PM with your scales + known ancestry and I will help you.
