The Human Organ Atlas paints a beautiful picture of the human body, with whole organs imaged down to the resolution of individual cells. These datasets are huge – each image is typically 1 TB, and across over 500 images we have collected more than half a petabyte of data. This immediately presents a challenge – how do we process and analyse datasets that are larger than the memory on our computers?

In this talk I’ll give an overview of the images in the Human Organ Atlas and use this to motivate the use of next generation chunked file formats. I’ll talk about how these chunked file formats work, the software being developing to help scientists work with these file formats, and ongoing work to develop a framework for memory-bounded computations.
