Hi! Thanks for the reply. The reason I would to smooth anisotropically is because we are analyzing functional spinal cord data (with anisotropic voxels too), which others have shown to have improved sensitivity of task activation when using anisotropic kernels to increase smoothing along the longitudinal axis of the cord.
As far as I can tell, none of those others have used an anisotropic method AND used a mask, which is something I am particularly interested in to reduce any smoothing of adjacent CSF or intravascular noise into the spinal cord. For this reason, I'm specifically interested in the masking capabilities of 3dBlurInMask, as well as using an anisotropic kernel.
