Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
DILATE A METRIC FILE wb_command -metric-dilate <metric> - the metric to dilate <surface> - the surface to compute on <distance> - distance in mm to dilate <metric-out> - output - the output metric [-bad-vertex-roi] - specify an roi of vertices to overwrite, rather than vertices with value zero <roi-metric> - metric file, positive values denote vertices to have their values replaced [-data-roi] - specify an roi of where there is data <roi-metric> - metric file, positive values denote vertices that have data [-column] - select a single column to dilate <column> - the column number or name [-nearest] - use the nearest good value instead of a weighted average [-linear] - fill in values with linear interpolation along strongest gradient [-exponent] - use a different exponent in the weighting function <exponent> - exponent 'n' to use in (area / (distance ^ n)) as the weighting function (default 6) [-corrected-areas] - vertex areas to use instead of computing them from the surface <area-metric> - the corrected vertex areas, as a metric [-legacy-cutoff] - use the v1.3.2 method of choosing how many vertices to use when calulating the dilated value with weighted method For all metric vertices that are designated as bad, if they neighbor a non-bad vertex with data or are within the specified distance of such a vertex, replace the value with a distance-based weighted average of nearby non-bad vertices that have data, otherwise set the value to zero. No matter how small <distance> is, dilation will always use at least the immediate neighbor vertices. If -nearest is specified, it will use the value from the closest non-bad vertex with data within range instead of a weighted average. If -bad-vertex-roi is specified, all vertices with a positive ROI value are bad. If it is not specified, only vertices that have data, with a value of zero, are bad. If -data-roi is not specified, all vertices are assumed to have data. Note that the -corrected-areas option uses an approximate correction for the change in distances along a group average surface. To get the behavior of version 1.3.2 or earlier, use '-legacy-cutoff -exponent 2'.
