Population-scalable genotyping from low-coverage sequencing data using pangenome graphs

COSIGT improves genotyping accuracy at low sequencing depths by matching coverage patterns to pangenome haplotypes using cosine similarity, enabling population-scale analysis of complex variation.

Fast and reliable ancestral reconstruction on ancient genotype data with non-negative Least square and Principal Component Analysis

ASAP uses PCA and NNLS to reliably estimate ancestry in admixed individuals, even with high missing data, and performs faster than existing tools.

Assessing temporal and geographic contacts across the Adriatic Sea through the analysis of genome-wide data from Southern Italy

The paper analyzes genome-wide SNP data from Southern Italy and neighboring regions to assess historical contacts and genetic affinities across the Adriatic Sea.

The genetic origin of Daunians and the Pan-Mediterranean southern Italian Iron Age context

The paper analyzes ancient DNA from Iron Age Apulian sites to explore the genetic origins of the Daunians and their place in the Pan-Mediterranean genetic landscape.

Projecting ancient ancestry in modern-day Arabians and Iranians: a key role of the past exposed Arabo-Persian Gulf on human migrations

The paper models ancestry in Arabians and Iranians, finding strong west-east population structure and evidence linking east Arabians to basal Eurasians.

Archaeogenomic Distinctiveness of the Isthmo-Colombian Area

The paper analyzes genomic data from Indigenous groups in Panama to reveal pre-Hispanic demographic changes and the genetic structure of the Isthmo-Colombian area.

The genomic impact of European colonization of the Americas

This study analyzes the genetic impact of European colonization on the Americas using genome-wide data from 12,000 individuals, revealing complex contributions from European, African, and other sources.

Genome-wide analysis of Corsican population reveals a close affinity with Northern and Central Italy

The paper analyzes genome-wide data from Corsicans and finds they are genetically closer to Northern and Central Italians than to Sardinians.

Population structure of modern-day Italians reveals patterns of ancient and archaic ancestries in Southern Europe

The paper analyzes the genetic structure of modern-day Italians to reveal ancient and archaic ancestries shaping Southern European populations and Neanderthal DNA distribution.
