Davidski G25 Standard model

[Eurafricanid]

Why would you have been reduced in America by the WHG and not the Tarofalt? The value of Tarofalt nailed, it is as if the algorithm assigned it to the Iberians by default.

Interesting you say that 'cause I have 0% Taforalt.

That's definitely interesting. It's probably some sort of overfitting going on since you have legitimate significant sub saharan dna. I know Tepecik has a slightly higher affinity to ssa compared to barcin but nothing significant enough to care.

It isn't accurate when used with my scaled IllustrativeDNA coordinates (made with raw data)

See:

26.2 Yamnaya_RUS_Samara
21.0 TUR_Barcin_N
11.6 WHG
4.8 MAR_Taforalt
0.4 Gambian



But when I run this calc DIRECTLY with my raw data (with this tool https://www.exploreyourdna.com/rawtosimg25.aspx ) I get a very accurate result, stereotypical spanish, nothing "off".

See:

Yours results on Davidski G25 Standard model :

TUR_Barcin_N: 54.35 %
Yamnaya_RUS_Samara: 31.21 %
WHG: 9.61 %
MAR_Taforalt: 4.28 %
TUR_Tepecik_Ciftlik_N: 0.56 %


When I upload the simulated coords made directly with the raw data through that tool (which i guess uses a similar algorithm to IllustrativeDNA, unless the coords in illustrativeDNA are manually created/"curated" [which I have no information about and I seriously doubt it]) to davidski calculator on vahaduo itself I get similar results to the ones made directly with the raw data (the raw data ones are more accurate cuz it has two decimal columns rather than only one, that is all the difference actually it seems)

I removed the tepecik reference and i got this with illustrativedna coords:

Kura araxes and ssa showing, the SSA being "noise"/miscall. Probably the "kura araxes" being too, since it doesn't show with the coords made with the rawdata-to-sim coords (when tepecik is removed, and kura araxes still there in the "source"/reference, meaning it should pop up)

Latest calculation I guess is the most accurate. Stereotypically spanish.

Mine get a bit weird with this RAW DATA Simulation:

Yours results on Davidski G25 Standard model :

Gambian: 38.07 %
TUR_Barcin_N: 29.69 %
Yamnaya_RUS_Samara: 14.11 %
Yoruba: 6.30 %
WHG: 5.36 %
ETH_4500BP: 3.71 %
BRA_LapaDoSanto_9600BP: 1.86 %
IRN_Shahr_I_Sokhta_BA2_I8728: 0.55 %
Han: 0.35 %
MAR_Taforalt: 0.01 %


They kind of show too much Gambian but the overall results look ok and the Taforalt looks very consistent, but the SSA makeup looks off and unrealistic, the overall results look sightly different, although similar.

[HelloGuys]

In this case theyre obviously wrong lol. "Fake" yet far more accurate and giving more convincing result than illustrative in both this calc and another peculiar one I have saved.

My farmer admixture is literally not TEPECIK lol this is needless to say and ur delusional if u believe so. I understand the eastern shift I got (I do have it. I'm shifted towards east med in the direction towards north italy) and its caused by CHG+the bit of Iran_N I have, which blended with my Barcin (because Barcin is the only actual type of anatolian farmer dna i have, just like any other iberian or even any italian for that matter and i dont have any recent italian admixture at all) gets read as "Tepecik". If anything the penultimate calculation made with my IllustrativeDNA coords would be the legit one (after removing the Tepecik reference, and having the CHG counted as "kura araxes" showing).

Yeah IllustrativeDNA is legit for the breakdown it gives you (hg&farmer) plus all the other calculations and fits within the app mostly. And maybe the coords themselves too. But in my case they don't work well when x component is added meaning I have to manually edit the calculators to get the most accurate result.

That's the reason you have to make your own models (Taking care you don't overfitting or underfitting).

Not even Davidski uses his own calculator (This one) because was made for everyone and not specifically for each person's individual ancestry.

is your iberian ancestry Portuguese?

That's definitely interesting. It's probably some sort of overfitting going on since you have legitimate significant sub saharan dna. I know Tepecik has a slightly higher affinity to ssa compared to barcin but nothing significant enough to care.

I don't think so, because Yoruba isn't an extemely North African-rich population itself to suck up much that much of the Taforalt. And even If I put SSA populations with even less NA affinity (0 or close to 0), like Mbuti and Nyaneka (South Angola) into the mix, the Talforalt is still not showing up.

It's only when I take out the Yoruba completely that 1% Taforalt appears. Not using the Yoruba is wrong in this case, since my black family's state recieved a lot of West African slaves, especially Yoruba.

Translation: "Because Bahia was closer to the Guinean Coast (West Africa) than to Angola, the majority of the black people from Bahia are Minas"

Mina (along with sudanese, sometimes) was the name west african slaves recieved in Brazil, comming from Nigeria, Ghana and that area.


Tepecik doesn't seem to have that affinity to SSA, it has a significant Natufian and Caucasus affinity, though.
