RegionCube: Create A Cuboid Region of Interest

In neuroim: Data Structures and Handling for Neuroimaging Data

Description

Create A Cuboid Region of Interest

Usage

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

Arguments

bvol	an BrainVolume or BrainSpace 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 BrainSpace then this argument is ignored.

Value

an instance of class ROIVolume

Examples

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