The main challenge was extending pandera-based schema validation to the complicated structure of SpatialData; Parquet and AnnData are easier!

Excited to share new preprint with NVIDIA on GPU-accelerated single-cell analysis 🚀

rapids-singlecell brings native GPU support to scverse/AnnData: hours → seconds (1M cells: ~52m → ~25s), scaling to 100M cells. Huge thanks to Severin Dicks 🙌

We're excited to announce that registration for our upcoming Spatial Omics workshop has opened!

Together with @ronghuizhu.bsky.social, we are thrilled to present our new perturb-seq study of 22M primary CD4+ T cells, across donors and timepoints – the result of a decade-long collaboration between the Marson @marsonlab.bsky.social and Pritchard @jkpritch.bsky.social labs 🧵 tinyurl.com/gwt2025

QCatch: A framework for quality control assessment and analysis of single-cell sequencing data Motivation: Single-cell sequencing data analysis requires robust quality control (QC) to mitigate technical artifacts and ensure reliable downstream results. While tools like alevin-fry and simpleaf (...

While we've been somewhat successful in spurring adoption of alevin-fry/simpleaf for scRNAseq processing, an impediment Dongze brought to our attention (now working directly w/ many experimentalists) was the need for a nice QC report for it's output; hence QCatch www.biorxiv.org/content/10.1... 1/x

First session

scverse conference 2025 done ✅ Really engaging week at Stanford with scPerturb-seq work, agentic models in biology, and strong interest in scaling software to millions of cells. Organizing alongside the rest of the @scverse.bsky.social team was a blast! Hope attendees found it productive 😄

Excited to see a home for MCP servers in bioinformatics emerge! The community needs a central hub for developing MCP servers for key bioinfo tools. At @scverse.bsky.social we're contributing to this effort - can't wait to share what we're building

Meet the keynote speakers for the 2025 scverse conference!

"Usability besides performance is also key."

Cannot stress this enough. There's a ton of methods out there that might not even be the best but are used because a substantial amount of time was invested into making it fast, accessible, and documented. Such methods are benchmarked in real use cases

Hi bioinformatics, genomics and CS friends! Please help me spread the word. I'm hiring a postdoc! Come work on cutting edge method development in algorithmic genomics with me and my group at @umdscience.bsky.social! 🖥️🧬

I see where you're coming from but what is your opinion on scientific-python.org/specs/spec-0... then? I find it valuable that the pydata ecosystem moves together.

My favorite part of last-year #scverse conference was to finally meet in-person many developers that I only knew from their GitHub username!

Submissions and travel grant applications close in 3 days. Find out more and apply at scverse.org/conference2025

@scverse.bsky.social

scVerse conference is at Stanford this year! Encourage folks (especially Bay Area/West coast folks) to sign up and attend. Cool workshops/talks and other events + great community of developers for one of the most widely used open source software for single cell data analysis!

It is pretty heart warming to see people start their really good pull request with "this is my first open source contribution. I hope that this is good.". Everyone starts somewhere and we're always happy to guide at @scverse.bsky.social .

Our benchmark + guidelines for atlas-level differential gene expression of single cells is online:

academic.oup.com/bib/article/...

Bottom line: Use pseudobulk + DESeq2 in simple and pseudobulk + DREAM in more complex settings.

Collab w/ @leonhafner.bsky.social @itisalist.bsky.social

I hate reference limits of journals so much. I'm sitting here trying to find a few more references to remove despite me knowing that I'll either remove context & evidence for scientific conclusions or not mention tools that very much deserve to be mentioned and cited.

Diagram showing MCP-enabled research architecture. Part A illustrates the flow between MCP servers (including BioContextAI Knowledgebase MCP and Community-developed MCP servers), Agentic systems connected via Model Context Protocol, and researchers asking research questions. MCP servers connect to knowledgebases and specialized software. Part B details the BioContextAI project components, divided into Registry (Schema.org ontology, Web interface, Open source licensing, MCP-enabled chatbot, Continuous integration) and Community (Documentation, Community forums, MCP server reviews, Shareable collections, Interoperability with tools like BioChatter).

Preprint alert 🚨 Do you use chatbots in your work or even build MCP servers and agentic systems yourself?

Or would you like to find a way to use biomedical tools using natural language?

Then check out biocontext.ai, now out on bioRxiv: www.biorxiv.org/content/10.1...

We will have our next community meeting on Tuesday, 2025-06-24 at 18:00 CEST! Sneha Mitra (@snehamitra.bsky.social) will speak about SCARlink.
(Zoom registration link and more information in thread!)

Happy to have this finally out! Check out the updated vignettes and if something is broken please open a GitHub issue and I'll have a look 😉👇
