Jun 1, 2025In 2025-06, delivered the MalariaGEN Ag3 Phenotype Data API integration in malariagen-data-python, enabling access to insecticide resistance phenotype data via PhenotypeDataMixin and AnophelesPhenotypeData within the Ag3 release. This work enhances data loading, merging, and filtering (including sample_query-based filtering) and enables seamless merging with SNP, haplotype, and genetic data. Introduced a constructor, comprehensive type hints, and dynamic sample coordinate handling; added a Jupyter notebook demonstrating end-to-end API usage and data integration. Completed a focused sequence of code-quality and stabilization tasks to ensure production readiness.
