Version Compatibility

Reference examples tested with: pandas 2.2+

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.

Gene ID Mapping

Python: mygene

Goal: Convert between gene identifier systems (Ensembl, Entrez, Symbol, UniProt) using the MyGene.info API.

Approach: Query mygene with source IDs, specifying scopes and target fields, to build an ID mapping dictionary.
