Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench.
FIND EXTREMA IN A CIFTI FILE
wb_command -cifti-extrema
<cifti> - the input cifti
<surface-distance> - the minimum distance between extrema of the same
type, for surface components
<volume-distance> - the minimum distance between extrema of the same
type, for volume components
<direction> - which dimension to find extrema along, ROW or COLUMN
<cifti-out> - output - the output cifti
[-left-surface] - specify the left surface to use
<surface> - the left surface file
[-right-surface] - specify the right surface to use
<surface> - the right surface file
[-cerebellum-surface] - specify the cerebellum surface to use
<surface> - the cerebellum surface file
[-surface-presmooth] - smooth on the surface before finding extrema
<surface-kernel> - the size of the gaussian surface smoothing kernel
in mm, as sigma by default
[-volume-presmooth] - smooth volume components before finding extrema
<volume-kernel> - the size of the gaussian volume smoothing kernel in
mm, as sigma by default
[-presmooth-fwhm] - smoothing kernel distances are FWHM, not sigma
[-threshold] - ignore small extrema
<low> - the largest value to consider for being a minimum
<high> - the smallest value to consider for being a maximum
[-merged-volume] - treat volume components as if they were a single
component
[-sum-maps] - output the sum of the extrema maps instead of each map
separately
[-consolidate-mode] - use consolidation of local minima instead of a
large neighborhood
[-only-maxima] - only find the maxima
[-only-minima] - only find the minima
Finds spatial locations in a cifti file that have more extreme values
than all nearby locations in the same component (surface or volume
structure). The input cifti file must have a brain models mapping along
the specified direction. COLUMN is the direction that works on dtseries
and dscalar. For dconn, if it is symmetric use COLUMN, otherwise use
ROW.
