Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
WEIGHTED SPATIAL STATISTICS ON A METRIC FILE wb_command -metric-weighted-stats <metric-in> - the input metric [-area-surface] - use vertex areas as weights <area-surface> - the surface to use for vertex areas [-weight-metric] - use weights from a metric file <weight-metric> - metric file containing the weights [-column] - only display output for one column <column> - the column number or name [-roi] - only consider data inside an roi <roi-metric> - the roi, as a metric file [-match-maps] - each column of input uses the corresponding column from the roi file [-mean] - compute weighted mean [-stdev] - compute weighted standard deviation [-sample] - estimate population stdev from the sample [-percentile] - compute weighted percentile <percent> - the percentile to find [-sum] - compute weighted sum [-show-map-name] - print map index and name before each output For each column of the input, a single number is printed, resulting from the specified operation. You must specify exactly one of -area-surface or -weight-metric. Use -column to only give output for a single column. Use -roi to consider only the data within a region. Exactly one of -mean, -stdev, -percentile or -sum must be specified. Using -sum with -area-surface (or -weight-metric with a metric containing similar data) is equivalent to integrating with respect to surface area. For example, if you want to find the surface area within an roi, do this: $ wb_command -metric-weighted-stats roi.func.gii -sum -area-surface midthickness.surf.gii
