Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
SMOOTH AND RESAMPLE VOLUME PARCELS
wb_command -volume-parcel-resampling
<volume-in> - the input data volume
<cur-parcels> - label volume of where the parcels currently are
<new-parcels> - label volume of where the parcels should be
<kernel> - gaussian kernel size in mm to smooth by during resampling, as
sigma by default
<volume-out> - output - output volume
[-fix-zeros] - treat zero values as not being data
[-fwhm] - smoothing kernel size is FWHM, not sigma
[-subvolume] - select a single subvolume as input
<subvol> - the subvolume number or name
Smooths and resamples the region inside each label in cur-parcels to the
region of the same label name in new-parcels. Any voxels in the output
label region but outside the input label region will be extrapolated from
nearby data. The -fix-zeros option causes the smoothing to not use an
input value if it is zero, but still write a smoothed value to the voxel,
and after smoothing is complete, it will check for any remaining values
of zero, and fill them in with extrapolated values.
Note: all volumes must have the same dimensions and spacing. To use a
different output space, see -volume-parcel-resampling-generic.
