Dataset quality is not perfect at all. Not enough coverage. Half of the individuals should be ignored because of missingness.

Actually: it is the Pop3 in the focus. We test if Pop3 is in the middle between pop1/pop2 or how far is pop3 on one side or another. This is good to know: F3(A,B,C) = F4(A,B, A,C) https://uqrmaie1.github.io/admixtools/reference/qp3pop.html In the description of the function they generaly...

They can use it both way: 1. To test if c is in the middle between a,b. 2. To test how far is c from a and b. F3=<(c-a)(c-b)>

p - the probability if there is a connection/ relation between pop2 and pop1 / pop3 se- standard error est - The estimated F3-statistics In your case here, there is no relation between pop2 and 2 others. The probability = 0. Z is too big and positive. If they were related - Z would be near 0...

Did you guys notice the huge amount of mtDNA haplogroup K1a with the new data? I see at least 108 individuals mostly from the new published data. This mit haplogroup is definitely connected to the Neolitic migration 12 k years ago. There are also 43 individuals with K1b mtDNA .

Did anyone else make a quality control on the new published data? What I am telling is that only 340 individuals have less than 40% missingness. The other 438 were not fully scanned or could not provide enough coverage details. Unfortunately the new published data is already mixed with the...

There is no need to use 7 components for such analisys, only 3 components should be used . Some of the components corelate to each other. By using 3 or max 4 components you will get more reliable results. More components will results in random categorization with one main component or another.

The data quality check on the latest dataset published by Lazaridis et al is showing there is a lot of Missingness per SNP / Missingness per individual . Only 336 individuals have less than 40% missingness.

How QC works in PLINK Missingness per SNP: --geno value Missingness per individual: --mind value Minor allele frequency: --maf value Some explanation for QC: genomicsbootcamp.github.io /book/genotype-data-quality-control.html

Hello guys, We have the latest data available for SouthernArc publications. The Zipped data has 5940 individuals, both previously known and new. The new data is for 778 individuals. Because of missing data, I had to do the full quality control on the provided data: plink --memory 12000...

Just a small correction. Forget about Kusunda people, it is about Kalasha. (My mistake, because I always mix them a little bit, however Kalasha are the IE, Kusunda are totally different language group). See: The Genetic Ancestry of Modern Indus Valley Populations from Northwest IndiaAjai K...

I was checking for similar connections with Kusunda people. Could you check what is the distance between Kusunda / Ror by using your system ? I have several other populations in the center, however we must admit this "center" was aslo the starting point for all other populations outside of...

What is this ROR population that you use to measure the distance ?

There is nothing from me about politics, there are some geographical locations when mentioning India or Pakistan. I think the origin of the first PIE should be located somewhere in Pakistan, but it could be also Afganistan or Iran. Because Iran is the place for mixture with Neolitic farmers...

Please admins to keep this discussion out of the politics. Science is not politically oriented. Few weeks ago I was thinking about proto-IE, and I was at similar opinion as the latest publication of the teams of Reich. In my opinion D. Reich is a little bit late with this publication, because...

I am not sure how reliable is this categorization. According to it, there are more slavic genes in Romania, compared to Bulgaria. And according to it, the Albanian population has almost the same amount of slavic genes compared to Bulgarians. I doubt this.

In fact the same statement could be made on the base of the existing data. Because Yamnaya did not add much variaty in the genetic connections between east-west. Yamnaya is just another way for the spread of IE people. However I suspect they will need to review all the dates in time , because...
