Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
DILATE A VOLUME FILE wb_command -volume-dilate <volume> - the volume to dilate <distance> - distance in mm to dilate <method> - dilation method to use <volume-out> - output - the output volume [-exponent] - use a different exponent in the weighting function <exponent> - exponent 'n' to use in (1 / (distance ^ n)) as the weighting function (default 7) [-bad-voxel-roi] - specify an roi of voxels to overwrite, rather than voxels with value zero <roi-volume> - volume file, positive values denote voxels to have their values replaced [-data-roi] - specify an roi of where there is data <roi-volume> - volume file, positive values denote voxels that have data [-subvolume] - select a single subvolume to dilate <subvol> - the subvolume number or name [-legacy-cutoff] - use the old method of excluding voxels further than the dilation distance when calculating the dilated value For all voxels that are designated as bad, if they neighbor a non-bad voxel with data or are within the specified distance of such a voxel, replace the value in the bad voxel with a value calculated from nearby non-bad voxels that have data, otherwise set the value to zero. No matter how small <distance> is, dilation will always use at least the face neighbor voxels. By default, voxels that have data with the value 0 are bad, specify -bad-voxel-roi to only count voxels as bad if they are selected by the roi. If -data-roi is not specified, all voxels are assumed to have data. To get the behavior of version 1.3.2 or earlier, use '-legacy-cutoff -exponent 2'. Valid values for <method> are: NEAREST - use the value from the nearest good voxel WEIGHTED - use a weighted average based on distance
