Create A Cuboid Region of Interest

Description

Create A Cuboid Region of Interest

Usage

cuboid_roi(bvol, centroid, surround, fill = NULL, nonzero = FALSE)

Arguments

bvol	an NeuroVol or NeuroSpace instance
centroid	the center of the cube in voxel coordinates
surround	the number of voxels on either side of the central voxel. A vector of length 3.
fill	optional value(s) to assign to data slot.
nonzero	keep only nonzero elements from bvol. If bvol is A NeuroSpace then this argument is ignored.

Value

an instance of class ROIVol

Examples

 sp1 <- NeuroSpace(c(10,10,10), c(1,1,1))
 cube <- cuboid_roi(sp1, c(5,5,5), 3)
 vox <- coords(cube)
 cube2 <- cuboid_roi(sp1, c(5,5,5), 3, fill=5)
