Not sure ….I would apply the same procedure to the whole image…

Hey thanks!
Might I ask another question?
If one were to apply a standard spatial smoothing kernel to just subsections of a functional image through the use of masks (e.g. use a mask to Gaussiansmooth just one subfield of the hippocampus), would the resulting smoothed image be problematic for use in analyses?Joshua

Subject: [FSL] Anistropic Spatial Smoothing Kernels
Hi all,
I am interested in using an anistropic kernel to spatially smooth high-resolution functional data. For example I'd want a 8mm FWHM in the z direction, but only 2 mm in z and y directions. In the structure I am examining, this appears to be a good way of increasing SNR while retaining spatial localization of activations to anatomical structures.
Has anyone done something like this before, and if so might I profitably use fslmaths to do so?-
