Our preprint on our new metagenomic HiFi assembler Alice is out 🥳 Based on a *new sketching method* (🧵1/6) 👉 Preprint www.biorxiv.org/content/10.1... 👉 Github github.com/rolandfaure/...

🌎👩‍🔬 For 15+ years biology has accumulated petabytes (million gigabytes) of🧬DNA sequencing data🧬 from the far reaches of our planet.🦠🍄🌵 Logan now democratizes efficient access to the world’s most comprehensive genetics dataset. Free and open. doi.org/10.1101/2024...

Preprint out for myloasm, our new nanopore / HiFi metagenome assembler! Nanopore's getting accurate, but 1. Can this lead to better metagenome assemblies? 2. How, algorithmically, to leverage them? with co-author Max Marin @mgmarin.bsky.social, supervised by Heng Li @lh3lh3.bsky.social 1 / N

I am happy to share our new preprint introducing MADRe - a pipeline for Metagenomic Assembly-Driven Database Reduction, enabling accurate and computationally efficient strain-level metagenomic classification. 🔗https://www.biorxiv.org/content/10.1101/2025.05.12.653324v1 1/9

Starting #RECOMBseq with @rayanchikhi.bsky.social 's keynote. Here stressing our responsibility as scientists to enable access to a common good: genomic data

Side note: you could, speaking purely theoretically, also fit every microbe onto an SD card, which is within the weight limit for a carrier pigeon. For some distances, it would be faster than the internet for transmitting sequence libraries 7/

So glad this is finally out. The method has been instrumental in allowing us to compress the AllTheBacteria data - ~2 million bacterial genomes shrink from 3Terabytes (gzipped) to 100Gb using phylogenetic compression. Great work by @brinda.eu

Do you (like me) create a bunch of conda environments, then later forget what they're for, when they were last updated, or which tools are in them? If so, you might this little project: github.com/rrwick/conda...

So glad to have participated in #DSB2025, what a great workshop! For some mysterious reason it was the first time I attended after 3 years of sequence research. Thanks to all participants & organizers 😃

Ragnar's made some incredible optimizations on the computation of minimizers, can't wait to see how these improvements will benefit bioinfo tools!

Amazing ideas here www.biorxiv.org/content/bior... from @yoann.bsky.social and collaborators. Reorganize minimizers to allow kmers dichotomic search. That's brilliant. #bioinformatics 🧬🖥️

So glad to have successfully defended my Ph.D. last week 😀 Work on producing haplotype-resolved metagenomic assemblies using noisy long reads (HairSplitter) and high-fidelity long reads (Alice assembler, unpublished yet). Thanks to my advisors Dominique Lavenier and Jean-François Flot ❤️
