Some days are harder than others. But at least today was a beautiful sunrise with the Moon and Venus

@imartayan.bsky.social pronounced my name incorrectly. Is it wrong of me to hope that generations of students and bioinformaticians to come will continue to do so?

I extended my fast-minimizers blogpost with the lastest results, providing proper deduplicated minimizers and super-k-mers in 1.65ns/kmer, and canonical kmers in 1.90ns/kmer. Or 5.4s and 6.4s respectively on a human genome.

Let me know if you want to use this :)

Nice result to end the day (night*):
After discussions with @imartayan.bsky.social, the SIMD minimizer code now also does proper canonical (revcomp) minimizers:

~1ns/bp for fwd minis
+0.4ns/bp with collect and dedup
+0.6ns/bp with canonical hashes.

Super happy how it's only 2x slower in the end!

Movi: A fast and cache-efficient full-text pangenome index Biocomputational method; Classification of bioinformatical subject; Genomic analysis

Very excited to see Movi (by @mohsenzakeri.bsky.social) now out in iScience: www.cell.com/iscience/ful.... Movi builds on the "move structure" pangenome index, a compressed full-text index and close cousin to r-index. Compared to r-index, the move structure is simpler and more cache-efficient.

It was not but I can redo the presentation in any other context ! This was basically the presentation of techniques like SSHash and why it is saving space and time.

The dpt started a new Primer Method session! The meeting will take place every Monday for 2 months. Today we had @hu-asch.bsky.social discussing interaction effect testing in linear models. Next week @yoann.bsky.social will talk about computing, storing and querying de Bruijn Graph from k-mer!

Salut les amis du ciel bleu. Si demain vous ne faites rien entre 15h et 19h, vous êtes les bienvenus à la Tréso à Malakoff pour jouer à la gameboy avec mon asso Benji et moi. Il paraît même qu'on y fera un tournoi de Tetris avec des cable link !

Ha par contre c'est un jeu où il faut surtout pas se spoiler. Tout doux sur les vidéos de gameplay sinon tu perd l'intérêt de l'exploitation du jeu.
