Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
MAP METRIC FILE TO VOLUME
wb_command -metric-to-volume-mapping
<metric> - the input metric file
<surface> - the surface to use coordinates from
<volume-space> - a volume file in the desired output volume space
<volume-out> - output - the output volume file
[-nearest-vertex] - use the value from the vertex closest to the voxel
center
<distance> - how far from the surface to map values to voxels, in mm
[-ribbon-constrained] - use ribbon constrained mapping algorithm
<inner-surf> - the inner surface of the ribbon
<outer-surf> - the outer surface of the ribbon
[-voxel-subdiv] - voxel divisions while estimating voxel weights
<subdiv-num> - number of subdivisions, default 3
[-greedy] - instead of antialiasing partial-volumed voxels, put full
metric values (legacy behavior)
[-thick-columns] - use overlapping columns (legacy method)
Maps values from a metric file into a volume file. You must specify
exactly one mapping method option. The -nearest-vertex method uses the
value from the vertex closest to the voxel center (useful for integer
values). The -ribbon-constrained method uses the same method as in
-volume-to-surface-mapping, then uses the weights in reverse. Mapping to
lower resolutions than the mesh may require a larger -voxel-subdiv value
in order to have all of the surface data participate.
