Sudanese Updated Results(23andMe vs FTDNA +pic)
Not really impressed by FTDNA, but overall I think 23andme is better in terms of ethnic breakdown and region assignment.

Some QpAdm Models of Various Pastoral Neolithic(PN) samples
Got somewhat bored today so I went and made some models, if you want to me to model something feel free to contact me.
As usual, all Z scores above two and all standard errors below 5 for optimal quality.
In total, only Kenya_PN_Elmenteitan and Kenya_EarlyPN showed levels of PPN that was consistent with a good Z scored but almost all other PN samples rejected it outright including Zagros weirdly. I made sure to double check thoroughly and honestly I don't know how to interpret some of these results so maybe someone can come up with an explanation for this.
You can model most PN samples as a two-way of Natufian and Dinka but this can be pushed further using a 3-way including Mota, and this seems to somewhat improve the p-value and fitting.
Let me know if I made a mistake or have any suggestions for improvisation.

QpAdm Models for Eritreans, Ethiopians, Somali & Pastoral Neolithic - Practically No ANF/Zagros presence in Pastoral Neolithic
All Z scores above two, good fits from my perspective.
Pastoral Neolithic Outgroups: Mbuti.DG, Iberomaurusian.AG, Ju_hoan_North.DG, Iran_TepeAbdulHosein_N.SG, SouthAfrica_2200BP.SG, Onge.SG, Chukchi.DG, Karitiana.DG, Georgia_Kotias_Mesolithic.SG, Papuan.DG

Strict Neolithic Modelling Attempt of East Africans
Three proto-nilotic sims was added to account for Mota-like affinity(East), Dinka-like affinity(West) and a more southern and central African-like(South) affinity or components that can't be captured by either mota-like or dinka-like. SSA ratios looks about right and distances are low for the most part. I think it could still be tweaked as SSA for Eritreans is too low so Eritreans could expect to get slightly weird results but I think its a good first attempt for the most part.
EDIT: forgot to include the coordinates...

Updated Raw Data File from Ancestry Worse?
Does anyone know what's the deal with the newer raw data file released? I heard that for genetic modelling, the raw data file offered by AncestryDNA is the gold standard due to its high coverage and SNP overlap, but now I'm hearing that they shrunk the raw file consideredably compared to previous years with much fewer SNPs compared to before. Does anyone have a breakdown on the SNP comparison between old and new as well as the SNP overlap for Eurogene/G25?

Post-March 2026 Raw Files?
Does anyone know how the newer raw files post-March of this year differs from older versions? Does it include more SNPs than before or the same, and can it be used to obtain G25 coordinates?

Will the new FTDNA family finder test NGS cover the same 700,000+ SNPs as before or will it be more than that?
The website claims: "The new panel will focus coverage on about 280 million base pairs of the human genome, which will include the approximately 700,000 SNPs previously reported from the GSA microarray chip." Does this mean that they will cover 700,000 or will it be more(undisclosed amount) but at least include 700,000?

What do you guys think of this new website?
Website: Ancestralgenome.com
Looks to be slightly better GUI-wise and more accurate than illustrative. They obtain their G25 from Davidski himself apparently and they include admixture breakdown for each component...
