Paper alert! We present Oreo a tools that reorder long reads datasets in a way to compress them efficiently with ANY universal compressor like gz, zstd, xz ... TLDR: You can get state of the art compression WITHOUT a dedicated compressor/decompressor! academic.oup.com/bioinformati... A thread!

I worked with Thomas during a three months research visit during his PhD, and it resulted in a paper in NAR. I highly recommend him. doi.org/10.1093/nar/...

Thomas Baudeau defended his thesis on Studying the properties of viral long reads mapping methods - congrats docteur Baudeau you'll be deeply missed in the team. I'm very glad I got the chance to work with you. Thomas is also on the lookout for a postdoc 👀

🧵1/n Estimating mutation rates using k-mers is fast—but what happens when repeats dominate the genome? In a new preprint, Haonan Wu, Antonio Blanca, and myself propose a *repeat-aware* estimator that's accurate even in centromeres.

Hey yeast lovers. Do you like pangenomes? O'Donnel et al. 2023 produced T2T assemblies of different strains, including phased haplotypes for yeast. Here I selected 10 phased haplotypes and the S288C reference, and looked for the MST28 / YAR033W gene reported to contain SVs such as indels. 👇🏻👇🏻

@alexanderjpetri.bsky.social's isONclust3 algorithm is now published doi.org/10.1093/bioi.... isONclust3 performs de novo clustering of long-read cDNA sequencing data. A key step in reference-free transcriptome analysis.

@tolyan.bsky.social is our very last speaker, on randstrobes ( high sensitivity seeds ) and their evolution the multi context seeds

2 in a row for @ksahlin.bsky.social (👋🏻👏🏻), first is @alexanderjpetri.bsky.social on de novo clustering of long read RNA, a problem that brings memories...

What is your all-time favorite data structure, and why? Respond or quote "skeet", and let us know what data structure we should all appreciate more! 🧬🖥

When “you’re on my list” has a different meaning. The list of alternative reviewer suggestions of course. 😈

I wrote a blog post a while back on a silly problem: how does the average contig length for an assembly relate to its N50? I "proved": N50 = (s * average contig length) for a constant s under exponentially distributed lengths. Interestingly, "s" = 1.6783469... and this is exact, not approximate

Excited to share our preprint introducing MGX 2.0, which adds metagenome (co-)assembly (including binning and bin assessment) as well as de novo metatranscriptome assembly.

What's a paper in algorithmic bioinformatics that you found inspirational or cool that maybe others don't know about? Reply and share a link. Extra points if it's not a paper written by close colleagues :)

Wow, just discovered this book recently published: Pearles of Algorithm Engineering. I've been wishing for a book like this! www.cambridge.org/core/books/p...

Whaaat, no bookmarks feature 👀 where should I store all the papers I never read 😳

"Minmers are a generalization of minimizers that enable unbiased local jaccard estimation" aka MashMap3 with Bryce Kille, @erikg.bsky.social, and @treangen.bsky.social is now accepted in Bioinformatics! Many thanks to the reviewers for their very careful reviews doi.org/10.1093/bioi...
