Dealing with multiple samples

Hi spatialdata folks,

I was wondering what is the intended way to work with images from different samples (e.g. 10 tumor slides from responders and 10 non-responders) when the goal is to compare features from groups with each other.

Would I still use 1 SpatialData object per sample and aggregate features elsewhere is it possible/recommended to store all images ein a single object?

Best,
Gregor
