PyDESeq2 Gene Expression Analysis

关于

The PyDESeq2 skill provides a comprehensive Python-based workflow for differential gene expression analysis, mirroring the industry-standard DESeq2 algorithm from R. It enables researchers and bioinformaticians to perform end-to-end transcriptomics tasks including data normalization, dispersion estimation, Wald testing, and log-fold change shrinkage. Designed to handle both simple case-control studies and complex multi-factor designs with batch effects, this skill integrates seamlessly with the Python data science ecosystem (pandas, AnnData) to turn raw count data into statistically significant biological insights.
