Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
CREATE SURFACE APPROXIMATING A CORTICAL LAYER
wb_command -surface-cortex-layer
<white-surface> - the white matter surface
<pial-surface> - the pial surface
<location> - what volume fraction to place the layer at
<out-surface> - output - the output surface
[-placement-out] - output the placement as a volume fraction from pial to
white
<placement-metric> - output - output metric
The input surfaces must have vertex correspondence. The output surface
is generated by placing vertices between the two surfaces such that the
enclosed volume within any small patch of the new and white surfaces is
the given fraction of the volume of the same patch between the pial and
white surfaces (i.e., specifying 0 would give the white surface, 1 would
give the pial surface).
