Yes, they fixed the pseudocount issue for fold-change which is good. Although despite trying we were unsuccessful in the Seurat and Scanpy teams coordinating their defaults and other implementation details following sciencedirect.com/science/ar…

The standard normalization is log(x/s*K 1) w/ K=10,000 in Seurat and Scanpy. It's been used in hundreds of thousands of studies. AI agents nowadays run it routinely. In an expansive benchmark in @naturemethods, Ahlmann-Eltze & Huber conclude it's pretty much best in class. 2/

I am a scanpy evangelist so I asked ChatGPT to implement for me ca. 2023, going to check the code now 😅

I saw that, but many bioinformaticians will never leave the scanpy API, and forcing people to copy paste this, edit it to make it work with an AnnData introduces friction and room for mistakes. Also this implementation densifies the data which would make it a no-go for my work

this is amazing work, but it would be 10x better if you also included code for using this method in scanpy/seurat workflows. Otherwise one of us will try, mess it up, and we will be right back here again

MiMo Code @XiaomiMiMo @_LuoFuli just launched with a free MiMo V2.5 channel (1M context). And I turned it into a bio agent: 1,676 biology SKILL.md files, one command to install. 735 skills run purely local (BioPython, scanpy, DESeq2 — no API key needed). Protein design suite (AlphaFold, RFdiffusion) uses Modal GPU — $30/mo free tier. github.com/BioTender-max/bio…
A strong model evolution needs a solid harness system, and vice versa. 14 days, 5 people, one vibe-coding journey — and MiMo Code was born. It's open source: github.com/XiaomiMiMo/MiMo-C…

The Seurat team was informed that Seurat "CLR" is problematic (e.g., github.com/satijalab/seurat/…), but that's a story for another thread. BTW Scanpy doesn't have a CLR implementation. So even though CLR is used frequently in, e.g. metagenomics, it is not in single-cell fields. 18/

We're especially interested in experts with deep, hands-on experience in the following area: Bioinformatics & Single-Cell Genomics Working with tools like scanpy, scvelo, squidpy, and gudhi for single-cell RNA-seq analysis, trajectory inference, spatial transcriptomics, and

Right, and it doesn't stop at retrieval. The same need runs up the whole analysis stack, and compbio has been building those layers for years (Bioconductor, scanpy, seurat). The trick isn't to reinvent them, it's to teach agents to use them. How I do it: modules, a skill plus an R/Python template script. The script templates one analysis, packages and all. The skill says when to fire it and what to watch for. The agent just bends varying inputs to fit, clean columns or messy samples alike, which is the kind of bounded task it's actually good at. Then chain them: Load/QC -> differential expression -> pathway -> plots. Will better models make harnesses like this unnecessary? For modules, the opposite. They keep your institutional knowledge enforced by construction, not rediscovered on every run, however good the model gets.

I can ask any chatbot how to run a differential expression analysis and get a decent explanation. What I actually wanted was something that runs scanpy on my data, hits the databases, and gives me the figures. So that's what we built. github.com/K-Dense-AI/k-dens…

Yessss! Wanted to share #STAMPede - a new Python toolkit for exploring and analyzing #STAMP data by @mhlangalab’s talented duo Niels Velthuijs and Siebren Frölich (mhlangalab.org) If you haven't heard of #STAMP yet…check this paper out cell.com/cell/fulltext/S0092……it's a single-cell method published in @CellCellPress last year, repurposing spatial-omics imagers to profile millions of cells at the lowest cost yet, without compromising data quality - no sequencing required. It retains cell morphology and supports multimodal profiling (RNA, protein, and HnE) all in one workflow. But powerful data needs powerful tools. That's where #STAMPede comes in. Built to handle the massive, shallow-depth datasets that #STAMP generates, #STAMPede gives you: → Familiar scanpy-style syntax so there's almost no learning curve → Full pipeline support: QC, filtering, binarization, dimensionality reduction, clustering, and differential expression → Easy installation via pip or conda Whether you're exploring rare cell populations or running large-scale perturbation studies, STAMPede is designed to keep up. Check it out 👉 siebrenf.github.io/stampede/ @DrJasPlummer #SingleCell #Bioinformatics #Genomics #OpenSource #STAMP #scRNAseq #ComputationalBiology
