One thing to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

🧬 RNA-seq Differential Expression

This skill performs differential expression on bulk RNA-seq or pseudo-bulk count matrices.

Core Capabilities

Input validation for count matrix and sample metadata
Pre-DE QC (library size, detected genes, low-count filtering)
PCA visualisation on normalized expression
Differential expression from formula + contrast
Volcano and MA plots
Markdown report with reproducibility files

Input Contract

Count matrix (.csv or .tsv): rows are genes, columns are samples, first column is gene identifier
Metadata table (.csv or .tsv): one row per sample, must include sample_id
Formula: e.g. ~ condition or ~ batch + condition
Contrast: factor,numerator,denominator (e.g. condition,treated,control)
