Hi, Melissa-

Are you wanting to take N subject's 3D ALFF volumes, stack them together into a N-by-3D dataset, and then calculate the voxelwise normalized "Z" value of each, based on the voxelwise mean and standard deviation?

There are different ways to slice the data, and that matters for order of operations and program(s) used.
