Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
ERODE A CIFTI FILE
wb_command -cifti-erode
<cifti-in> - the input cifti file
<direction> - which dimension to dilate along, ROW or COLUMN
<surface-distance> - the distance to dilate on surfaces, in mm
<volume-distance> - the distance to dilate in the volume, in mm
<cifti-out> - output - the output cifti file
[-left-surface] - specify the left surface to use
<surface> - the left surface file
[-left-corrected-areas] - vertex areas to use instead of computing
them from the left surface
<area-metric> - the corrected vertex areas, as a metric
[-right-surface] - specify the right surface to use
<surface> - the right surface file
[-right-corrected-areas] - vertex areas to use instead of computing
them from the right surface
<area-metric> - the corrected vertex areas, as a metric
[-cerebellum-surface] - specify the cerebellum surface to use
<surface> - the cerebellum surface file
[-cerebellum-corrected-areas] - vertex areas to use instead of
computing them from the cerebellum surface
<area-metric> - the corrected vertex areas, as a metric
[-merged-volume] - treat volume components as if they were a single
component
For all data values that are empty (for label data, unlabeled, for other
data, zero), set the surrounding values to empty. The surrounding values
are defined as the immediate neighbors and all values in the same
structure within the specified distance (-merged-volume treats all voxels
as one structure).
The -*-corrected-areas options are intended for eroding on group average
surfaces, but it is only an approximate correction.
