Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
ERODE A LABEL FILE
wb_command -label-erode
<label> - the input label
<surface> - the surface to erode on
<erode-dist> - distance in mm to erode the labels
<label-out> - output - the output label file
[-roi] - assume values outside this roi are labeled
<roi-metric> - metric file, positive values denote vertices that have
data
[-column] - select a single column to erode
<column> - the column number or name
[-corrected-areas] - vertex areas to use instead of computing them from
the surface
<area-metric> - the corrected vertex areas, as a metric
Around each vertex that is unlabeled, set surrounding vertices to
unlabeled. The surrounding vertices are all immediate neighbors and all
vertices within the specified distance.
Note that the -corrected-areas option uses an approximate correction for
distance along the surface.
