1. What is the recommended space label to refer to the head coordinates (in subject space, not normalized) coming from the voxel-to-world transformation sform coming from a .nii file immediately after converting from DICOM?
   "head", "world", "ras", "orig", "subject"?

2. Is it OK to specify only MNI152, or should we always specify the full template name? (eg. MNI152NLin6)
   If the latter: does anybody know what to indicate when using an affine SPM12 registration (spm_maff8)?
