In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

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 representing the cuboid region of interest, containing the coordinates and values of voxels within the specified region.

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)
