We introduce a Python implementation of ANCOM-BC that is 100x faster than the original R code, while preserving statistical validity. Scales to much larger omics datasets and enables ML workflows with repeated inference (feature selection, sensitivity, stability, etc.) #Bioinformatics #Microbiome

skbio.stats.composition.ancombc — scikit-bio 0.7.1 documentation Perform differential abundance test using ANCOM-BC.

ANCOM-BC in Python! scikit-bio 0.7.1 introduces a native implementation of this widely used differential abundance test. Same validated methodology, consistent results, and blazing fast! Scalable to very large datasets. Try it out: scikit.bio/docs/latest/... #Bioinformatics #Microbiome #OpenSource

@xrefugee13.bsky.social I might have an idea to "save" Bacillota by measuring phylogenetic rejection. Let me email you.

Good to know! People may say that more observations offer more chances to break a hypothesis (Bacillota's monophyly). Taxon sampling vs. method robustness is always a dilemma...

Making Bacillota monophyletic probably isn't easy. I've been thinking that a taxonomic group should be splitted only when there's strong phylogenetic evidence rejecting its monophyly (instead of supporting). This can probably resolve lots of "_A" suffixes.

However, we have limited examples of how these pr...

Skin bacteria are subject to dispersal and chance across 22 amphibian species, yet contemporary and historical contingencies (e.g., #phylosymbiosis) leave strong signatures in their microbiomes even at large geographical scales.

Our method selects any number of markers that perform as well as or better than currently adopted markers of this number. More is better. More contains less. Paralogs okay. One can tweak it to bias toward well- or pooly-studied microbial genomes.

Thrilled to share our new preprint on finer and flexible marker gene selection for microbial phylogenomics. Given any input genomes and an arbitrary number, it will find this number of useful markers. Effective with highly incomplete MAGs. www.biorxiv.org/content/10.1...

We conducted fluorescence-activated single-cell sorting of active predatory protists in the ocean and recovered symbionts with cool evolutionary positions close to animal pathogens.
