I'm getting horrible results when making PCAs with ancient samples, Im using the v62 1240k dataset
they all bunch up in the same place
here i changed the numoutevec number to 15 and added modern samples(red square) too
again the same problem, they all plot more or less together not making...
That error you get is a Linux basic, its because the spaces, instead of "John Smith" try "John_Smith" or "JohnSmith" and just modify the outer column, the "control" one
uh, now I understand something...
yeah thats what they do, here you have a lot of modern (and ancient) samples from other studies

check supplementary data from studies, for example
(from...
kinda unrelated but what do u think about v54.1 1240k vs v62 1240k? v62 is ofc more up to date but I see weird samples and labels and the v54 seems more curated or "refined"? which one do you use? I get slight differents results
At the end I did the merge with both plink and eigensoft, the two work okay.
Where did you get hold of v62.0?

haha you are a bit confused, the Z-score in qpAdm is calculated by dividing the weight between the standard error(calculate it yourself, you will see how it matches), so of course you want the z score to be high! imagine your model gets 0.54 or 54% of Turkey_Barcin and only 0.0180/1.8% of SE...
Where did you read that? Z-score should be over 1.5 or 2 to be significant, the more the better, more Z-score = more robustness/certainty.
It estimates how much given ancestry proportions differ from the expected value (https://en.wikipedia.org/wiki/Expected_value).
I think its impossible to get...
hmm, do you have the same number of SNPs in your merged files of different formats? my merged v54.1.p1_HO.bim file got 597k SNPs, pretty good considering my raw DNA data from MyHeritage had a bit over 600k SNPs, but the .snp file that I got as a result of merging with v54.1.p1_1240K and...
