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.
