    Turkish Eurogenes Basal-Rich K7 & Globe10 Data Request

    I've been dabbling with some nMonte ancients modelling for Iranians over the past few days and wanted to produce some decent results for modern Turks as well. However, the Basal-Rich K7 public spreadsheet only features "Turkish" and "Turkish Trabzon" populations. If there's enough traffic here, I'm intending to share the results on my research blog, including maps and some basic statistics.

    I'd appreciate receiving results for any individuals (including related) who are entirely of ancestry from the modern Turkish state. If anyone shares results for Turks with ancestry from outside the modern Turkish state, including Turkish-related groups (i.e. Pomak, Meshkhetian Turks), I'll happily run their data through my setup, but I won't include their data in the aforementioned blog entry.

    Code:
    [1] "distance%=1.0938 / distance=0.010938"
    
             Turkish:average
                            
    Levant_N:average    48.8
    Iran_N:average      25.0
    Yamnaya:average     15.1
    Altai_IA:average    11.1
    Paniya:PNYD3         0.0
    Sintashta:average    0.0
    SSA_Excess           0.0
    Loschbour:Loschbour  0.0
    
    
    [1] "distance%=1.3495 / distance=0.013495"
    
             Turkish_Trabzon:average
                            
    Levant_N:average    61.9
    Iran_N:average      20.9
    Yamnaya:average     17.3
    Paniya:PNYD3         0.0
    Sintashta:average    0.0
    SSA_Excess           0.0
    Loschbour:Loschbour  0.0
    Altai_IA:average     0.0
    A few comments:
    - Iran_N + Levant_N + WHG combo to mirror Anatolian_BA (per Lazaridis et al.). Also accounts for any surplus of any component. I tried a synthetic, but it didn't produce fits anywhere near as good.
    - Altai_IA is there for obvious reasons.
    - EMBA and LNBA steppe samples (Yamnaya and Sintashta respectively) consolidated into averages.
    - Paniya and SSA present for additional atypical admixture.

    I tried this generic setup with Armenians and Iranians. The results were as anticipated. Armenians lacked East Eurasian admixture and possessed roughly equivalent Yamnaya to Turks (see below). This setup isn't ideal for Iranians (ideal looks like Iran_ChL + Iran_N + LNBA + East Eurasian, both for nMonte and qpAdm).

    Code:
    [1] "distance%=1.4388 / distance=0.014388"
    
             Armenian:average
                            
    Levant_N:average    55.8
    Iran_N:average      29.1
    Yamnaya:average     15.2
    Paniya:PNYD3         0.0
    Sintashta:average    0.0
    SSA_Excess           0.0
    Loschbour:Loschbour  0.0
    Altai_IA:average     0.0
    Thank you!

    Dear DMXX,
    I'd like to volunteer for your research,having all known recent ancestry from Turkey. However, I might need instructions "For dummies".

    Do you just need results of Eurogenes_ANE K7?

    All I need is the K7 and Globe10 personal results from one of the Eurogenes runs from last year.

    This information can't be retrieved from an online calculator. Davidski directly sends the data to participants after receiving an appropriate fee.

    I'd prefer Globe10 over K7, in case volunteers were wondering!

    Does it matter if such a sample has origins in Balkans and had turkish speaking ancestors (obviously not bosnians,or albanians etc)?

    ^ If I'm going to be creating plots showing the variation of various components across Anatolia, most certainly, since they're not originally from Anatolia.

    I've offered to run our Turkish members irrespective of background through this nMonte setup irrespective, however.

    I've had a look at the blog for K7 and Globe10. It seems complicated to me. Even if I was able to follow all the steps, I doubt that the results are going to be beyond my comprehension.

    Need more reading first..

    ^ Have you participated in K7/G10? If you have, all I'd require are your results.

    I've located the Turkish sub-groups from Davidski's older spreadsheet. Will share the results here shortly for everyone's viewing pleasure. Performing these with globe10.

    [Edit]: Made some changes. The problems I had with the K7 Anatolian aDNA samples doesn't seem to occur with G10. Introducing several Anatolian aDNA averages and adding Nganasan+Han for East Eurasian (some of the Altai_IA scores were beginning to exceed 30%; Turkish LNBA heritage is getting absorbed by that).

    My suspicion?

    I don't think the "Iran_N" is truly from Iran in most of the models (at least in an informative sense). Time-predicated stratifying of Anatolian samples across the region hasn't happened just yet. I suspect much of the "Iran_N", particularly in the eastern and southern half of Turkey, is a local variant of Anatolian_ChL/BA that happens to have an excess of this component relative to what has been defined by Lazaridis et al.

    I do, however, think some of it is real and was introduced by the Oghuz Turks (and those that followed them) via Khorasan. Combine that with Nganasan, Han and some portion of the West Eurasian steppe (a proportion of the excess relative to Armenians?), it looks reasonable to assume the waves contributed at least 20%.

    So, none of the turkish regional samples pick up ALTAI_IA but the so called 'turkish' does?

    As stated in post #8, I removed Altai_IA and replaced it with Nganasan and Han. I made the switch specifically to clear up the degree of East Eurasian admixture. Altai_IA and Karasuk are both predominantly LNBA steppe with significant East Eurasian admixture. Ergo, an Altai_IA component will be particularly high among the Balikesir and Aydin samples.

    I don't anticipate there was any significant Sintashta-like/"pure" LNBA steppe ancestry in Anatolia (odds are reasonable that any Cimmerian and Scythian input would have been EMBA, going by the Sarmatian samples). I included that in the first run to see whether any patterns emerged. It only popped up among the Kayseri sample.

    This run was useful as it gives us an approximate range for the EMBA steppe (~2-20%) and East Eurasian (~1.5-13%) admixture among modern Turks with Anatolian roots. It served its' purpose.

    In the next run, I'll be dropping Nganasan, Han, Sintashta and Boncoklu and adding Altai_IA back in (or Karasuk_outlier, depending on which is more East Eurasian). That should also address the slight overfitting seen above.

    It's a work-in-progress, but I figured everyone would appreciate seeing the process from start to finish.

    [Edit]: I've configured a pretty neat pan-West Asian setup that would theoretically work for South and North Caucasus pops, Armenians, Kurds, Iranians and Assyrians. Depending on the results, I might share the results. If nothing more comes of it, you know I'm not satisfied with the statistical fits.
