Extract searchlight pattern from a SPM

For a provided spm object and a mask of voxel the function extracts the values of the parameter estimates within the searchlight region and for all voxel in the mask.

getSearchlightPattern(spm, voxel, radius)

Arguments

spm	an object of class 'fmrispm'
voxel	a mask (logical) with dimensionality compatible to the spm
radius	radius of the searchlight

Value

an array of dimension c(nb, nsl, nvox) with nb the number of estimated parameters in spm$beta, nsl the number of voxel in the searchlight and nvox the number of voxel in the mask provided as second argument
