Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.

Ie: it's not us (Samtools team)! Be warned

It's taken more than 2 years but we can officially announce anndataR!

There's still a lot of features to add but we hope a robust, "official", R-native H5AD reader/writer will unlock the defacto single-cell storage format for R users by avoiding issues with current solutions like zellkonverter.
We're excited to share that our preprint on anndataR, a new package bringing Python's AnnData to R, is now available on bioRxiv 🎉

This week in my graduate-level Science Communication course, we are discussing communicating science to the public through public speaking (i.e., museum "evening with a scientist" nights, Nerd Nite lectures, speaking at community events, etc).

What advice do you have to share with my students? 🧪

Analyzing your single-cell data by mapping to a reference atlas? Then how do you know the mapping actually worked, and you’re not analyzing mapping-induced artifacts? We developed mapQC, a mapping evaluation tool www.biorxiv.org/content/10.1... from the ‪@fabiantheis lab. Let’s dive in🧵

There is no reason to stay bound to one programming language. I discussed ways to ease R-Python interoperability with Luke Zappia, Philipp Angerer, Tomasz Kalinowski.

Our latest study in @science.orgAdvances explores how glucocorticoid exposure—a key environmental risk factor—shapes early human brain development using #organoids.

Do any #rstats reticulate experts have examples of using register_module_help_handler() or register_help_topics()? I feel like these should be able to let a package provide access to help information but there isn't much documentation on how to use them.

Thought for computational biologists choosing projects:

If you’re interested in method development, one counterintuitive strategy can be to dive deep into biology.

I just uploaded the first version of {{exactplot}} to github.com/const-ae/exa... 🎉

It produces figures with consistent font size, Latex labels, and millimeter-perfect layouting. It's an alternative to patchwork with less elegant syntax but much more flexibility.
