How do you turn a CT scan of a pig into usable data for large-scale genetic research? At Topigs Norsvin, we scan 10,000 male pigs each year using high-resolution CT imaging. This allows us to look inside the animals and assess carcass quality, muscle composition, and indicators of health. We use this data to inform selection decisions and improve the accuracy of our breeding program. In this talk, I'll walk you through the journey of CT data: from scan acquisition and processing to how we extract traits and integrate them into the breeding program. A key part of this process is POSIT, a lightweight project structure that helps us manage complexity, ensure reproducibility and scale our pipelines effectively. While the biological context is specific, the data challenges are familiar to any data professional.
