Name

spatialsmooth-sess - 3D Gaussian ["Smoothing"] using ["FSL"] IP

Synopsis

spatialsmooth-sess -i [instem] -o [outstem] -fwhm [fwhm] -s [sessid] or -sf [sessidfile] -d [srchdir] or -df [srchdirfile] [<options>]

Positional Arguments

-s [sessid] or -sf [sessidfile]

-d [srchdir] or -df [srchdirfile]

Optional Flagged Arguments

-fsd [fsdir]

-noinorm

do not intensity norm smoothed volume

Outputs

[outstem]

smoothed volume

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.
