🦒Long read giraffe is out!🦒
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

Our work looking at the effects of using autosomal assumptions for calling variation on X and Y. We used simulated data to compare to a ground truth.

Tldr: Accurate ploidy is important for reducing false positives; appropriate alignment reduces false negatives.

Best practices for improving alignment and variant calling on human sex chromosomes
Sex chromosome complement is the largest karyotypic variation observed in humans. X and Y chromosomes were once a pair of homologous autosomes. Although chromosome X and Y differentiated from one anot...

The human pangenome continues to grow and improve! Release 2 is here! Click through for the details, but this is a pretty amazing dataset including not just the phased assemblies, but PacBio HiFi, ONT Ultralong, Dovetail/Illumina Hi-C, PacBio Kinnex, and Illumina WGS for all samples
