Unifying package managers, workflow engines, and containers: Computational reproducibility with BioNix.

Abstract

MOTIVATION: A challenge for computational biologists is to make our analyses reproducible-i.e. to rerun, combine, and share, with the assurance that equivalent runs will generate identical results. Current best practice aims at this using a combination of package managers, workflow engines, and containers. RESULTS: We present BioNix, a lightweight library built on the Nix deployment system. BioNix manages software dependencies, computational environments, and workflow stages together using a single abstraction: pure functions. This lets users specify workflows in a clean, uniform way, with strong reproducibility guarantees. AVAILABILITY AND IMPLEMENTATION: BioNix is implemented in the Nix ex..
