voxel_select.RdTakes the difference in T2 images, smoothes this difference, and then finds voxels greater than one SD of the smooothed mask as potential voxels and returns it
voxel_select(normalized_baseline_t2, normalized_follow_up_t2, brain_mask,
sigma = diag(3, 3), ksize = 5)| normalized_baseline_t2 | Baseline T2 image, array or object class nifti that |
|---|---|
| normalized_follow_up_t2 | Followup T2 image, array or object class nifti that |
| brain_mask | A 3D 0-1 mask that delimits where the smoothing occurs, passed to |
| sigma | Sigma passed to |
| ksize | Kernel size passed to |
Array or object class nifti depending on imput iamges
