Hi Ze Wang,

indeed, the AnnArborB site has only 16 voxels in the z-direction, including only the top part of the brain. I'm sorry you had to find this out after processing the data!

However, I would not say the data should be removed. They can still be useful for people who are not interested in the bottom parts of the brain (e.g., they might only be interested in motor cortex). With appropriate registration algorithms it is possible to use these data.

Again, sorry you had to find this out after starting your preprocessing. I hope you're still enjoying the rest of the data!!
