During October 2024, Francisco Martinez Pico focused on streamlining the nf-core/sarek bioinformatics pipeline by removing the unsupported Strelka tumor-only somatic variant calling method. He refactored the Groovy and Shell codebase, updated XML-based test configurations, and revised documentation to ensure consistency and clarity. This work reduced the maintenance burden and improved pipeline reliability by eliminating obsolete functionality, thereby aligning the project with supported variant calling approaches. Francisco’s efforts demonstrated a strong grasp of Nextflow pipeline development and bioinformatics best practices, resulting in a cleaner, more reproducible workflow that minimizes user confusion and supports ongoing maintainability for the repository.
