I think you flipped them on both axes, can you flip them only on component 2 axis. If imposible, leave them the way they were. They are so different they should not plot that close. Could you check the numbers again please.

I've inverted the two principal components, PC2 on X axis, PC1 on Y axis.

The numbers seem correct (I had already checked them). But tomorrow morning I check them again.

This is the common direction used on PCA, try to flip it these directions. Europe to the left, near east to the right, Neolithic South.

So I guess people enjoy messing with nMonte bc they either don't understand it or want to show off how "group x" they are? If it doesn't go by actual genes I fail to see how useful it is.

You fit anywhere in central Balkans: Bosnia, Serbia, Romania, Bulgaria or even Macedonia. Perhaps you are mixed, because I can't pinpoint your exact ethnicity. Your caucasian is more like Bosna-Serbia. Your NE Euro and SW Asian sits between Serbia and Bulgaria. Your Mediterranean admixture is good for all central Balkans.
Definitely, not from Madagascar. ;)

I am northwest romanian.

About the other results what can you say?

Thanks!
 
Rob/Gravetto performed this interesting global10/basal rich7 pca with all the main ancient samples


Italy North = Italian_Bergamo:HGDP

Tuscan = Italian_Tuscan:NA

Greek = Greek:GREEKGRALPOP = Greek Thessaloniki (more north you can't go in Greece)

East Sicily = Italian_Sicilian_East:EastSicilian

Sth Italy = Italian_South:SouthItalian

Sardinian = Sardinian:HGDP

Too bad that the only South Italian sample everyone seems to be using is that strange one that has terrible FST with virtually everyone.

In fact. What is the origin of that sample?

Strange also that the Thessaloniki sample is used to represent all the Greeks; it is like a sample from Treviso was used for all Italians.

I e-mailed them to ask but they wouldn't tell me out of privacy concerns. If I remember correctly they said it was on the Ionian side. I should probably e-mail them again and tell them how strangely this sample behaves, and that they might be using a highly drifted and not very representative sample for South Italians.

I've been complaining about the samples used for some of these countries for years, not that anyone cares. In addition to the actually Thessalonian sample used for Greece (which is why it plots so close to Toscana), there's the half Catalan sample used for Iberia. If you listen to the Catalans, they're in no way Iberians, and that includes genetically! :)

Hold on. I see that there's no Iberian sample in this particular plot, only one labeled Catalan. If it's the oft used academic sample, it's actually half Catalan. Generally, it's pretty clear to me that Iberians list north not because of additional "Celtic", given that they have so little "steppe" ancestry, but because they absorbed a bit more WHG than people in the southeast.

These researchers seem to have blind spots that won't be dislodged by "amateurs" e-mailing them. Take, for example, the Hellenthal/Busby supposed analysis of "recent" dna absorption. I think a lot of it is wrong or at least questionable. For example, I'm not sure they can tell if there was an inflow of more southeastern, Greek like (farmer heavy) dna into more central Euro type people in Italy after the fall of Rome, or the opposite, i.e. "Celtic", "Lombard" admixture into a much more "Mediterranean" population, which they date too late because as is always the case with the program they use, it picks up only the date of the latest admixture.

Iberian are genetically homogeneous, there's been millions of Northern Spaniards who migrated to Andalusia, because the Moors has been expelled, so there's virtually no genetic difference between Northern and Southern Spaniards.

So South Italians almost make it halfway between Cypriots and Thessalonian Greeks. Where's their Germanic influence? That should make them more Northward towards Swiss or Austrians.
 
Is someone updating the calculator? Last I checked, Zack, author of this calculator, has stopped working on it.

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.

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.

Yes, quite normal, though you plot closer to average Romanian than Bulgarian.

Caucasian element came from CHG, Anatolian and Iranian Farmers. It was also reintroduced in Europe by Anatolian BA.
