I would like to take a step back and ask what you want this data to look like? If you do not want the structure unionization data, do you want something like the data described [in this section of the documentation](https://community.brain-map.org/t/api-for-allen-developing-mouse-brain-atlas/2855#p-5144-expression-gridding-6) (gene expression quantified over a 3D grid of the brain)?
