Query the CELLxGENE Census (61M+ cells) programmatically. Use when you need expression data across tissues, diseases, or cell types from the largest curated single-cell atlas. Best for population-scale queries, reference atlas comparisons. For analyzing your own data use scanpy or scvi-tools.
# CZ CELLxGENE Census ## Overview The CZ CELLxGENE Census provides programmatic access to a comprehensive, versioned collection of standardized single-cell genomics data from CZ CELLxGENE Discover. This skill enables efficient querying and analysis of millions of cells across thousands of datasets. The Census includes: - **61+ million cells** from human and mouse - **Standardized metadata** (cell types, tissues, diseases, donors) - **Raw gene expression** matrices - **Pre-calculated embeddings** and statistics - **Integration with PyTorch, scanpy, and other analysis tools** ## When to Use This Skill This skill should be used when: - Querying single-cell expression data by cell type, tissue, or disease - Exploring available single-cell datasets and metadata - Training machine learning models on single-cell data - Performing large-scale cross-dataset analyses - Integrating Census data with scanpy or other analysis frameworks - Computing statistics across millions of cells - Accessing pre-calculated embeddings or model predictions ## Installation and Setup
