Reproducible Research

---

• Modern scientific research is complex and requires software environments.
• Computational reproducibility helps to enable reproducible science.
• New technologies make all of these processes easier.
• Reproducible computational software environments are a first step toward fully reusable scientific workflows.

Introduction to Pixi

---

• Pixi uses a project based workflow and a declarative project manifest file to define project operations.
• Pixi automatically creates or updates a hash level lock file anytime the project manifest or dependencies are mutated.
• Pixi allows for multi-platform and multi-environment projects to be defined in a single project manifest and be fully described in a single lock file.

Backwards compatibility with conda

---

• If you need to use conda, you can export Pixi workspace environment to formats conda can use.
• Exporting conda explicit spec files from Pixi locked environments provides the ability to create the same hash level locked environment with conda that Pixi solved.
