1/ Excited to share our preprint ImpuT2T: a pangenome-based assembly patching tool ImpuT2T scaffolds draft human assemblies with a pangenome (HPRC2) and patches gaps by leveraging linkage disequilibrium and sequence identity between contigs and reference haplotypes Code: github.com/maojanlin/Im...

ImpuT2T: Pangenome-Based Patching for Human Genome Assemblies

With improvements in sequencing and assembly have come many high-quality telomere-to-telomere assemblies and reference pangenomes. However, the long-read sequencing recipes needed for high quality ass...

1/ Excited to share the newest tool in the pangenome MUMiverse: Shredtools! Shredtools enables a user to navigate the pangenome coordinate system with multi-MUMs. More in the thread🧵 Code: github.com/vikshiv/shredtools Interactive tool for querying HPRC assemblies: vikshiv.github.io/shredtools

Navigating the pangenome coordinate system with Shredtools

Existing notions of pangenome coordinates rely on hard-to-compute multiple sequence alignments. On the other hand, pangenome-wide exact unique matches (multi-MUMs) can be computed efficiently, and rep...

Time for a thread on our Christmas preprint “Origin and evolution of acrocentric chromosomes in human and great apes”. I had so much fun with this project and paper. It will be hard to summarize in a thread, but I’ll try www.biorxiv.org/content/10.6... [1/21]

Excited to share a preprint for (w/ @benlangmead.bsky.social) our new tool, Mumemto, on biorxiv! Mumemto finds multi-MUMs across pangenomes (i.e. mummer but for pangenomes). It can rapidly visualize synteny, identify misassemblies, and accelerate core genome and multiple alignment, highlighting SVs.

Mumemto: efficient maximal matching across pangenomes

Aligning genomes into common coordinates is central to pangenome analysis and construction, but it is also computationally expensive. Multi-sequence maximal unique matches (multi-MUMs) are guideposts ...
