Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
SMOOTH PARCELS IN A VOLUME SEPARATELY
wb_command -volume-parcel-smoothing
<data-volume> - the volume to smooth
<label-volume> - a label volume containing the parcels to smooth
<kernel> - the size of the gaussian smoothing kernel in mm, as sigma by
default
<volume-out> - output - the output volume
[-fwhm] - smoothing kernel size is FWHM, not sigma
[-fix-zeros] - treat zero values as not being data
[-subvolume] - select a single subvolume to smooth
<subvol> - the subvolume number or name
The volume is smoothed within each label in the label volume using data
only from within the label. Equivalent to running volume smoothing with
ROIs matching each label separately, then adding the resulting volumes,
but faster.
