Function: randomSearchlight()

function randomSearchlight(mask, radius): ROIVolWindow[];

Defined in: src/searchlight/searchlight.ts:226

Create a spherical random searchlight iterator.

This function generates a spherical random searchlight iterator for analyzing local neighborhoods of voxels within a given radius in a brain mask. The algorithm randomly selects centers and removes all voxels within the searchlight from future consideration.

Parameters

mask

| NeuroVol | LogicalNeuroVol

A NeuroVol object representing the brain mask

radius

number

The radius of the searchlight sphere (in mm)

Returns

ROIVolWindow[]

Array of ROIVolWindow objects
