In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

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 signature 'NeuroSpace,matrix'
grid_to_grid(x, vox)

## S4 method for signature 'matrix,matrix'
grid_to_grid(x, vox)

Arguments

x	the object
vox	a matrix of LPI voxel coordinates

Value

A numeric matrix of native 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)
