where each axis could be the organizational hierarchy. The project/dataset/
images hierarchy is effective in grouping AGEMAP images by organ, but
other groupings, based on individual mouse, age, sex, and diet (see Fig. 18.5),
can also be organized. There is significant value in the other groupings. Viewing
images by individual mice can help elucidate if there are staining variations in
slides or any per-mouse outliers. Analyzing images in age-, sex-, and diet-
matched groups makes it possible to look for structural biomarkers of age,
sex, and diet, which is a key objective of AGEMAP.
OME provides a parallel structure to projects/datasets/images called ...
