The La Brana appears to show some affiliation to 1000k Iberian samples or at least some of them. It may suggest its partly continuity for the Iberians living today vs the ancient La Brana.

Do anyone know what affiliation the La Brana individuals had in previous analysis done by others except for the official research paper?

Not a project update but a pilot study confirming everything is alright with the La Braña individuals genotypes extracted.

I have now done a first initial test run with a few especially Northern European populations consisting of both reference panels and project participants. I cant find the connection Vadim Verenich claimed to have found between the La Brána and the Saami or at least not to that extend he seem to have found it. As I understand the found connection was as large as 80%.

Looking forward to this

What are you finding instead, just that the connection isn't as strong as Vadim had thought?

Difficult to say. I will not claim at Vadim's wrong. In the Chromopainter-Finestructure with a very small dataset of North-Europeans individuals the BRA composite individual appears to show the strongest affiliation first with the Lithuanians and secondary with some Finns. The affiliation to the Saami appears more distant. However the Lithuanians had affiliations with other populations the BRA individuals didn't have in that run. On the other han I just run a K2-K7 run with 63k in ADMIXTURE. At K7 the BRA clustered with what appear to be a North-East Europe component that peaks in Finns and Saamis and to less extent among Scandinavians and showed no affiliation with Lithuanians who peaked in a Eastern European cluster that goes all the way to the Chuvash.
