BootstrapSearchlight {neuroim}

Create a searchlight iterator that samples regions from within a mask. Searchlight centers are sampled *without* replacement, but the same voxel can belong to multiple searchlight samples. It is in the latter sense that this is a bootstrap resampling scheme.

Description

Create a searchlight iterator that samples regions from within a mask. Searchlight centers are sampled *without* replacement, but the same voxel can belong to multiple searchlight samples. It is in the latter sense that this is a bootstrap resampling scheme.

Usage

BootstrapSearchlight(mask, radius, iter = 100)

Arguments

mask

an image volume containing valid central voxels for roving searchlight

radius

in mm of spherical searchlight

iter

the total number of searchlights to sample (default is 100)
