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)
