Create A Spherical Region of Interest

Usage

RegionSphere(bvol, centroid, radius, fill = NULL, nonzero = FALSE)

Arguments

bvol	an BrainVolume or BrainSpace instance
centroid	the center of the sphere in voxel space
radius	the radius in real units (e.g. millimeters) of the spherical ROI
fill	optional value(s) to assign to data slot
nonzero	keep only nonzero elements from bvol

Value

an instance of class ROIVolume

Examples

 sp1 <- BrainSpace(c(10,10,10), c(1,1,1))
 cube <- RegionSphere(sp1, c(5,5,5), 3.5)
 vox = coords(cube)
