Since barcin might mask some Natufian. I used Aktopraklik instead and the margion of error is lower than the percentage.

Try Boncuklu ANF too. That group seems to have low Natufian.

I will

I'm experimenting again with modern populations.

[Xavier727]

What reference populations did you use? I’m still trying to figure out which ones work best for modern samples, so far my results have been a bit inconsistent.

[Gannicus]

Admixture modeled some ANFs and a Greek EEF:

Greece NeaNikomedeia EN:



Catalhoyuk:



Boncuklu:



Barcin:



And this is a Barcin ANF individual that I have used myself with my own models. His/her genome and mine go together well.



My results with Bar25:



And another run with a few tweaks in the references:




G25:

Target: Gannicus_MergedFile_officialDavidski_scaled
Distance: 0.0450% / 0.04499545
47.2 Russia_Samara_EBA_Yamnaya
41.6 Turkey_Marmara_Barcin_N:Bar25__BC_6366__Cov_99.86%
11.2 Luxembourg_Mesolithic:Loschbour_snpAD__BC_6075__Co v_92.30%



Edit: Had to fix the screenshots.

I've produced successful models using Mesolithic/Neolithic sources like EHG,AHG,WHG, Natufian etc. And I'm still experimenting, but so far when I use the Karelia EHG the model fails. The model works with Veretye EHG though. And this latest model is with a slight adjustment to the references used in the previous runs.

This modern one is the closest. I don't know how accurate these are due to no Irish in the samples. I think Norway.HO is the best to use because there are more samples. Also Norway.HG is too close to me and seems too Isles shifted. With the selection of populations there is not a lot of others I can use. All other combinations come out FALSE.



I tried English with Spanish but this is an example of a FALSE model for me.



Here is my fst list with mostly European populations. I think the Norwegian.HG and also the Polish one might be outliers (both are only 1 sample). So I think Norway.HO is more accurate for distance and to model with.

Your model is close to your G25. Good to know. I'll try this for myself.

I'm doing some ancient models

I want to see what my medieval mix is so I'm going with this. I know I'm a sort of Gaelic/Scandinavian mix from G25. Although I rationalise this as having high Steppe because I think G25 and also qpAdm is inflating Scandinavian. Is there any samples that I could use to resolve this?

This model was accepted.



With Anglo-Saxon it was rejected.



I'll experiment further with models. There is a lack of Irish ancient samples and no modern day Irish reference so I feel a bit frustrated about that. I wish there was more Gaelic samples. I'll see if there are Picts and if they would be more suitable.

I'll look at some bronze age models over the coming week.

I haven't had much luck using two ancient Northwest Europeans as sources. Even if I use a third "Southern" population. It does the same thing you are seeing. I guess qpAdm struggles to figure out where the Steppe is coming from.
