Description
spatialsmooth-sess performs 3D Gaussian spatial Smoothing using the FSL IP program. It will operate on the input volume in each run. The output volume will be placed in the same directory. FWHM is the full-width, half-maximum of the spatial filter gaussian (sigma = fwhm/2.36).
Examples
Example 1
spatialsmooth-sess -s sessid -d sessdir -i fmc -o fmcsm5 -fwhm 5
Smooth the motion corrected volume with a gaussian kernel with FWHM of 5 mm. The result will be placed in the volume fmcsm5. This is the stem that should be referenced when creating the anlysis. It will also automatically run intensity normalization (ie, inorm-sess) for the smoothed volume unless -noinorm is specified.
