Version Compatibility

Reference examples tested with: pandas 2.2+, scanpy 1.10+, scikit-learn 1.4+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures
• R: packageVersion('<pkg>') then ?function_name to verify parameters

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

Automated Cell Type Annotation

CellTypist (Python)

Goal: Automatically annotate cell types using a pre-trained or custom CellTypist model.

Approach: Load a reference model, predict cell types with majority voting for cluster-level consensus, and add predictions to AnnData.
