Hello,

I have been using the 3dBlurInMask function to smooth my fMRI data with a mask of the spinal cord. There is currently only the option to enter a FWHM to define an isotropic kernel. I would like to be able to use an anisotropic kernel with a mask, but there is currently no option in this function. (Nor can I do it in 3dBlurToFWHM, which I gather can perform the same/similar function to blur within a mask).

Unless there is some other way to perform anisotropic smoothing within a mask - is this a function that can or will be added?

Thank you!!

- Kim
