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 VOLUME FILE
wb_command -volume-weighted-stats
<volume-in> - the input volume
[-weight-volume] - use weights from a volume file
<weight-volume> - volume file containing the weights
[-match-maps] - each subvolume of input uses the corresponding
subvolume from the weights file
[-subvolume] - only display output for one subvolume
<subvolume> - the subvolume number or name
[-roi] - only consider data inside an roi
<roi-volume> - the roi, as a volume file
[-match-maps] - each subvolume of input uses the corresponding
subvolume 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 subvolume of the input, a single number is printed, resulting
from the specified operation. If -weight-volume is not specified, each
voxel's volume is used. Use -subvolume to only give output for a single
subvolume. Use -roi to consider only the data within a region. Exactly
one of -mean, -stdev, -percentile or -sum must be specified.
Using -sum without -weight-volume is equivalent to integrating with
respect to volume.
