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.
