Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
ESTIMATE FWHM SMOOTHNESS OF A VOLUME
wb_command -volume-estimate-fwhm
<volume> - the input volume
[-roi] - use only data within an ROI
<roivol> - the volume to use as an ROI
[-subvolume] - select a single subvolume to estimate smoothness of
<subvol> - the subvolume number or name
[-whole-file] - estimate for the whole file at once, not each subvolume
separately
[-demean] - subtract the mean image before estimating smoothness
Estimates the smoothness of the input volume in X, Y, and Z directions
separately, printing the estimates to standard output, in mm as FWHM. If
-subvolume or -whole-file are not specified, each subvolume is estimated
and displayed separately.
