scanpy
Performs Scanpy single-cell RNA-seq QC, normalization, HVG selection, PCA/UMAP/t-SNE, clustering, exploratory marker ranking, pseudobulk preparation, visualization, and Seurat or SingleCellExperiment RDS conversion to h5ad. Applies to established exploratory scRNA-seq workflows with explicit count and expression provenance; complementary skills cover scvi-tools models and AnnData format details.

# Scanpy: Single-Cell Analysis
## Overview
Scanpy is a scalable Python toolkit for analyzing single-cell RNA-seq data, built on AnnData. Apply this skill for complete single-cell workflows including quality control, normalization, dimensionality reduction, clustering, marker gene identification, visualization, and trajectory analysis. Targets **Scanpy 1.12.4** (released 2026-08-27), reviewed 2026-10-01. Native synthetic tests establish data/API contracts, not biological validity.
## Installation
Requires Python **3.12+** (scanpy 1.12 dropped Python ≤3.11) and anndata **≥0.10**.
```bash
uv pip install "scanpy[leiden]"
```
