What is the CZ CELLxGENE Census?

The CZ CELLxGENE Census is a comprehensive, versioned collection of standardized single-cell genomics data from CZ CELLxGENE Discover, providing programmatic access to millions of cells.

How do I avoid duplicate cells in my analysis?

The skill provides patterns that recommend always filtering for 'is_primary_data == True' in your queries to ensure you are analyzing unique cells.

How do I ensure my research is reproducible?

The skill emphasizes specifying the 'census_version' when opening the data to ensure that analyses can be replicated against exact data snapshots.

Can I use this for machine learning?

Yes, this skill includes specific patterns for integrating Census data with PyTorch using experimental data loaders designed for large-scale model training.

Does this skill handle memory-intensive queries?

Yes, it provides workflows for out-of-core processing using axis_query and iterative processing to handle datasets that exceed available system RAM.
