 # OPTIONAL: Registration with -initwarp requires pre-registration, but in some cases you won't have an anatomical image to do a pre-registration. So, as an alternative, you can register the template directly to a metric image. For that, you just need to create one or two labels in the metric space. For example, if you know that your FOV is centered at C3/C4 disc, then you can create a label automatically with:
-# sct_label_utils -i mt1_seg.nii.gz -create-seg -1,4 -o label_c3c4.nii.gz
+# sct_label_utils -i mt1_seg.nii.gz -create-seg-mid 4 -o label_c3c4.nii.gz
 # Then, you can register to the template.
 # Note: In case the metric image has axial resolution with thick slices, we recommend to do the registration in the subject space (instead of the template space), without cord straightening.
