Developed an end-to-end ANARCII integration for the nf-core/modules repository, enabling automated antigen receptor numbering and CSV output generation from FASTA inputs within Nextflow pipelines. The work involved configuring reproducible environments, updating Singularity containers, and implementing comprehensive tests to ensure reliable results across different architectures. Using Groovy and YAML, the developer refactored and formatted code to align with project standards, while also updating test data and expectations to accommodate score variations. This integration streamlines annotation workflows in bioinformatics, reduces manual effort, and enhances interoperability with downstream analytics, positioning nf-core/modules for scalable, standards-compliant analysis in containerized environments.
