Scanpy Single-Cell Analysis

An end-to-end Scanpy workflow skill for scRNA-seq: QC, normalization, PCA/UMAP, Leiden clustering, markers and cell-type annotation.

Data & AnalyticsAdvanced33,0303,248AI score 9/10Last updated: Aug 9, 2026

What it does

  • Runs the standard single-cell RNA-seq pipeline with Scanpy: quality control → normalization/log1p → highly variable genes → PCA/UMAP/t-SNE → Leiden clustering → marker genes → cell-type annotation.
  • Prefers a bundled CLI toolkit in scripts/ (run_pipeline.py, inspect_data.py, qc_analysis.py, preprocess.py, reduce_dimensions.py, batch_correct.py, cluster.py, find_markers.py, annotate.py, plot.py, …) — all .h5ad-in/.h5ad-out so steps chain cleanly.
  • Also covers batch integration (harmony/bbknn/combat), Scrublet doublet detection, gene-signature scoring, pseudobulk aggregation for DE, and publication-quality plotting.
  • Includes an R interop runbook for converting Seurat / SingleCellExperiment .rds or .RData objects into .h5ad.

Who it's for

  • Bioinformaticians and grad students analyzing scRNA-seq datasets.
  • Anyone who needs to explore 10x Genomics output or h5ad files quickly.
  • R/Seurat users migrating data into the Python scverse ecosystem.

Example uses

  1. One-shot analysis: python scripts/run_pipeline.py raw.h5ad -o processed.h5ad --resolution 0.5 --n-top-genes 2000 --scrublet produces a clustered object plus figures and marker CSVs.
  2. Multi-sample integration: add --batch-key sample --batch-method harmony to correct batch effects before UMAP/clustering.
  3. Iterative annotation: inspect per-cluster marker CSVs, write a celltypes.json mapping, run annotate.py, then plot.py --kind dotplot --genes CD3D CD14 --groupby cell_type for a figure.

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/scanpy folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/scanpy/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/K-Dense-AI/scientific-agent-skills.git /tmp/sci-skills && mkdir -p ~/.claude/skills && cp -r /tmp/sci-skills/skills/scanpy ~/.claude/skills/

This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/K-Dense-AI/scientific-agent-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r scientific-agent-skills/skills/scanpy ~/.claude/skills/
  5. Install dependencies in a Python 3.12+ environment: uv pip install "scanpy[leiden]" (or pip install "scanpy[leiden]").
  6. Restart Claude Code and ask something like "use the scanpy skill to QC and cluster this h5ad file".
  7. If your input is an R object (.rds/.RData), follow references/r_interop.md to install R and the conversion packages first.
