1/ Bioinformatics takes years to master.
Not because it’s hard.
But because so much of what matters… no one writes down.
Let me explain

I’ve recorded ~8h explaining the architectures of AlphaFold, AF2 & AF3, as well as the context needed to understand their development, applications and limitations :)

Sooo happy to finally have this one published!! (3 years in the making… 👀) A comprehensive investigation into the recency and geographical origins of both SARS-CoVs that spilled to humans in the past few decades, now in @cp-cell.bsky.social www.cell.com/cell/fulltex...

Tools like bowtie assume that a space on your fasta header is the end of the header and will trim it out, which is annoying if you have pair-end sequencing. Although bowtie has its own command to avoid this, a good practice could be replacing spaces with '_', this can be done using awk or sed.

My replies are perpetually full of anti-vaxxers these days telling me about polio vaccines.

Not shockingly, most of what they are saying is wrong. Luckily, I trained with Vincent Racaniello & he taught me a few things about poliovirus.

So let’s discuss the king of the Picornaviridae👇🏻
