resels: Estimates image resels

Description Usage Arguments Details Value Author(s) References See Also Examples

View source: R/resels.R

Description

Utilize the estimated FWHM to find the resels per voxel

Usage

1
resels(mask, fwhm)

Arguments

mask

statistical value (typically the maxima of a cluster or statistical field)

fwhm

the full width at half maxima measurement

Details

Interprets a given antsImage mask (binarized so as to only contain 0s and 1s) into resolutions elements (as opposed to voxels). Doing so emphasizes the interdependent nature of voxels when undergoing RFT based statistical analyses. Optimized for three dimensions.

Value

A vector of resels for dimensions 0:D
