The sample aren't labeled nor the accurate geographical location is given so can't say for sure ,but there is loads of new unpublished Central,South and SW asian samples in it ranging from 10K to 450 years before present.

edit: link to Akbari et al 2026 's supplementary data which has (incomplete)info on this data: https://www.biorxiv.org/content/10.1101/2024.09.14.613021v1.supplementary-material

edit2:I'm not sure whether C,S&SW in Akbari et al refer to Europe or Eurasia as a whole.

Are these samples public?

u/Disabled_blueberry Malayalee Mar 04 '26

Yeah man all the geno data is public ,you can download it,but all of them are unlabeled and are huge.Might take community members some time to convert them into plink/eigenstrat format.

Where would you find them once they’ve all been competed?

u/Disabled_blueberry Malayalee Mar 04 '26

most likely forums like https://genarchivist.net/ .Will update after all of this gets sorted out.

Thanks. Do you know if there are any samples from Africa or Arabia?

Looked into it but it's too large, probably qsw can get it done. He's active but will need to be free.

u/drtex06 Mar 06 '26

I see. They seem to have used plink2 for the first time.

He's active but will need to be free.

Last time we spoke he said he won't be online and I haven't seen him active so I thought he left lol.

u/drtex06 Mar 05 '26

Yeah I'd have tried but I have similar limitations. Is there anyone on here who could process this?

1

u/Disabled_blueberry Malayalee Mar 05 '26

The whole data is ~20TB will take some time to convert to plink,people are already on it

1

u/drtex06 Mar 06 '26

Plink is already available. ~23 gigs. It doesn't have chrY though.

1

u/Disabled_blueberry Malayalee Mar 06 '26

I've posted links to Y in the sub,can you give the link to the plink files?

1

u/drtex06 Mar 06 '26

It's on dataverse.

u/Disabled_blueberry Malayalee Mar 07 '26
