Are you screening your ancient DNA study for chromosomal aneuploidies? Or looking for a new way to call genetic sex? Regardless of sequencing data type? Our Bayesian method (implemented in R as RChASM) has now been published in Bioinformatics: doi.org/10.1093/bioi...

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! www.biorxiv.org/content/10.1...
