Of course it's odd. There are no Greeks and Iberians on HGDP to begin with.

The academic samples, especially in the past, are never released in a format compatible with Gedmatch, they need to be converted to a build 37 format. I think something may have gone wrong in this conversion process.

I meant that it shouldn't be there in a PCA, in that position. The PCA is better than the Oracle, the latter is more deceptive. The Oracle for the individual Tuscan HGDP chooses all Spaniards as the first population (and the Spaniards in a PCA are in a secluded position, certainly not at the...

In the PCA the Tuscan kit goes close to the Spaniards, while Catanzaro is south of Southern Italian samples. Unusual results or bad calculator?

Its based on MDLP 16 modern spreadsheet. I did the PCA because I was asked and I removed many ethnicities because so PCA was more readable. And among these I also removed France South because in fact it seems just another Basque sample, as you can see in the PCA below. North Italian samples...

Hi! one PCA for many users

Yes, more or less. Often results are groundless, it is who uses it to decide which models to use, nMonte alone doesn't determine which are the best samples.

I've tried but not possible with the soft I'm using. I'm learning a new statistical software package, I hope to succeed within a very short time.

You're atypical even for Italian standards. Of course the Italian component doesn't imply "Italian ancestry".

I have great doubts about the theoretical framework behind the K36, I have the feeling that all the samples available were used and then the components were created. But 22% is quite a normal score for both Tuscans and Bergamasks. Lombards, Emilians, Ligurians usually score around 24/25% as...

I don't know if they are from Lyon. But even French have very low percentages of French component. French usually have more Iberian and Italian than French. FR_Bretagne has slightly more "French" than other French. That K36 map made by Aha can be deceptive, especially in this case. In bold...

For Italian: Bergamo + Tuscans. For Iberian: all the Iberian samples; for West Med: Sardinians.

Me too, I don't find K36 particularly accurate either. There is a txt file with all the K36 reference samples. The reference sample for the French component (the one from Lyon?) French French_HGDP00511 0 0 0 -9 French French_HGDP00512 0 0 0 -9 French French_HGDP00513 0 0 0 -9 French...

To the best of my knowledge, Near Eastern component is based on Jordanians, Lebanese Muslims, Syrians and Palestinians. French is based on a French sample of people from Central France.

K15 PCA based on same kits.
