Dimensionality reduction and clustering for single-cell RNA-seq using Seurat (R) and Scanpy (Python). Use for running PCA, computing neighbors, clustering with Leiden/Louvain algorithms, generating UMAP/tSNE embeddings, and visualizing clusters. Use when performing dimensionality reduction and clustering on single-cell data.

Excerpt From SKILL.md

Scanpy (Python)

Goal: Reduce dimensions, build neighbor graphs, cluster cells, and visualize with UMAP/tSNE using Scanpy.

Approach: Run PCA for dimensionality reduction, construct a k-NN graph, apply Leiden community detection, and compute UMAP embedding.

"Cluster cells and find groups" → Reduce dimensionality with PCA, build a neighborhood graph, partition cells into clusters, and embed in 2D for visualization.

Visualize variance explained

sc.pl.pca_variance_ratio(adata, n_pcs=50)

Visualize PCA

sc.pl.pca(adata, color='n_genes_by_counts')

Use cases

  • Use for running PCA, computing neighbors, clustering with Leiden/Louvain algorithms, generating UMAP/tSNE embeddings, and visualizing clusters.
  • Use when performing dimensionality reduction and clustering on single-cell data.

Not for

  • Do not rely on this catalog entry alone for installation or maintenance details.
