grid_to_grid: Generic function to convert voxel coordinates in the reference space (LPI) to native array space.

Description

Generic function to convert voxel coordinates in the reference space (LPI) to native array space.

Usage

grid_to_grid(x, vox)
# S4 method for NeuroSpace,matrix
grid_to_grid(x, vox)
# S4 method for matrix,matrix
grid_to_grid(x, vox)

Value

A numeric matrix of native voxel coordinates.

Arguments

x

the object

vox

a matrix of LPI voxel coordinates

Examples

# Create a simple 3D volume in LPI orientation
space <- NeuroSpace(c(10,10,10), c(2,2,2))

# Create a reoriented space in RAS orientation
space_ras <- reorient(space, c("R", "A", "S"))

# Convert coordinates between orientations
voxel_coords <- t(matrix(c(1,1,1)))
new_coords <- grid_to_grid(space_ras, voxel_coords)
print(new_coords)
