we made a tool!
ybyra is a lightweight, flexible Y-chromosome haplogroup caller. It is faster, easier to tune and more robust than other tools particularly for low-coverage or ancient DNA data. And it has lots of detailed output – including plots!

The genetic history of Portugal over the past 5,000 years - Genome Biology Background Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasi...

🇵🇹Our paper on Portugal's genetic history is now published in Genome Biology. We present Portugal’s largest ancient genome collection, with deeper analyses than our pre-print, revealing migrations, admixture & continuity shorturl.at/TcErC

Thank you, Bastien 🙏 Grateful for your mentorship and trust from the start. It’s always a pleasure working with you and I'm proud of what we built together as a team

Optimized in-solution enrichment of over a million ancient human SNPs - Genome Biology Background In-solution hybridization enrichment of genetic markers is a method of choice in paleogenomic studies, where the DNA of interest is generally heavily fragmented and contaminated with enviro...

Excited to share our new paper! We benchmarked the Twist Ancient DNA kit for in-solution enrichment. It’s cost-effective, robust, and shows no allelic bias, even when pooling libraries!
