Mapping long reads to pangenome graphs is ~10x faster than with GraphAligner, with veeery slightly better mapping accuracy, short variant calling, and SV genotyping than GraphAligner or Minimap2

A complete diploid human genome benchmark for personalized genomics
Human genome resequencing typically involves mapping reads to a reference genome to call variants; however, this approach suffers from both technical and reference biases, leaving many duplicated and ...

🚨 Pre-print alert! 🚨
We generated chromosome-scale diploid genome assemblies for the widely used fibroblast lines BJ and IMR-90.
These models of replicative senescence and telomere shortening now have fully resolved telomeres, subtelomeres, and centromeres. 🧬
