Featured

Run differential gene expression analysis on bulk RNA-seq count matrices with PyDESeq2, the Python port of DESeq2 — size-factor normalization, dispersion estimation, Wald tests, FDR (Benjamini-Hochberg) correction, and volcano/MA plots. Use when identifying differentially expressed genes between conditions from raw bulk RNA-seq counts. Part of the AlterLab Academic Skills suite.

# PyDESeq2 ## Overview PyDESeq2 is a Python implementation of DESeq2 for differential expression analysis with bulk RNA-seq data. It supports complete workflows from data loading through result interpretation, including single-factor and multi-factor designs, Wald tests with multiple-testing correction, optional apeGLM shrinkage, and integration with pandas and AnnData. ## When to Use This Skill Use this skill when: - Analyzing bulk RNA-seq count data for differential expression - Comparing gene expression between experimental conditions (e.g., treated vs control) - Performing multi-factor designs accounting for batch effects or covariates - Converting R-based DESeq2 workflows to Python - Integrating differential expression analysis into Python-based pipelines - Users mention "DESeq2", "differential expression", "RNA-seq analysis", or "PyDESeq2" ### Does NOT Trigger | Scenario | Use Instead | |----------|-------------| | Single-cell differential expression or cluster marker genes | `alterlab-scanpy` (markers) or `alterlab-scvi-tools` (model-based DE) | | Turning FASTQ into the count matrix (salmon/kallisto/STAR quantification, tximport) | `alterlab-rnaseq-quant` | | Generic regression / GLM / mixed models on non-count data | `alterlab-statsmodels` | | Somatic or germline variant calling from sequencing reads | `alterlab-nf-core-sarek` | | Microbiome feature-table differential abundance | `alterlab-qiime2-amplicon` | ## Installation and Requirements ```bash uv pip inst...

bulk-rnaseq-counts-to-de-deseq2

Run differential expression analysis on bulk RNA-seq count data with DESeq2 (R). Covers DESeqDataSet construction from a count matrix, tximport (Salmon/Kallisto), featureCounts, or SummarizedExperiment; pre-filtering; design formulas (simple, batch, paired, interaction, multi-factor, LRT); result extraction by coefficient or contrast; log-fold-change shrinkage (apeglm/ashr); VST/rlog transformations; and exporting significant genes. Use when the user has RNA-seq counts and wants differential expression, DE genes, volcano/MA inputs, or a DESeq2 workflow.

alterlab-rnaseq-quant

Quantifies bulk RNA-seq transcript abundance with salmon 2.x (the Rust rewrite; selective alignment or --sketch) and kallisto (v0.52.0, kb-python workflow), builds a decoy-aware gentrome index, runs quant with --gcBias -l A, then imports estimates via tximport/tximeta with a tx2gene map and hands differential expression to alterlab-pydeseq2. Warns that salmon 2.0 cannot read C++/pufferfish indices (rebuild every index), that --validateMappings is now accepted-but-ignored, and that 'salmon alevin' was REMOVED (single-cell now uses piscem + alevin-fry). Use when quantifying RNA-seq transcript abundance, running salmon or kallisto, building a decoy-aware index, or wiring tximport to DESeq2; for differential expression use alterlab-pydeseq2, for FASTQ-to-VCF variant calling use alterlab-nf-core-sarek.
