Version Compatibility

Reference examples tested with: Cell Ranger 8.0+, anndata 0.10+, numpy 1.26+, pandas 2.2+, scanpy 1.10+

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.

Single-Cell Data I/O

Read, write, and create single-cell data objects for analysis.

Scanpy (Python)

Goal: Load, create, and save single-cell data objects using Scanpy and AnnData.
