PyDESeq2 is a Python implementation of the popular DESeq2 R package, specifically designed for performing differential gene expression analysis on bulk RNA-seq count data.

What input data is required?

It requires a raw count matrix (non-normalized integers) where rows are samples and columns are genes, along with a metadata DataFrame containing experimental factors.

Does it support LFC shrinkage?

Yes, the skill includes patterns for apeGLM shrinkage, which reduces noise in fold change estimates for genes with low counts or high dispersion.

Can I use this for single-cell RNA-seq?

PyDESeq2 is optimized for bulk RNA-seq. However, it is frequently used in single-cell workflows for 'pseudobulk' analysis, where counts are aggregated by cluster or sample.

How does this skill handle batch effects?

You can account for batch effects by including them in the design formula, such as '~batch + condition', which allows the model to control for technical variation.
