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).
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.
