Examples

library(oro.nifti)

# Path of the example files (with large voxels to ensure the example runs quickly)
mask_path = system.file("examples", "mask.nii.gz", package = "nifti.pbcor")
img1_path = system.file("examples", "img1.nii.gz", package = "nifti.pbcor")
img2_path = system.file("examples", "img2.nii.gz", package = "nifti.pbcor")

# Prepare the mask
mask = nifti.pbcor_mask(readNIfTI(mask_path))

# Conduct the parcel-based correlation
nifti.pbcor(readNIfTI(img1_path), readNIfTI(img2_path), mask)
