Probabilistic spinal level masks: what is the metric? (sct_warp_template -s)

SCT v4.3

Hi SCT forum,

What do the voxel values represent in the probabilistic spinal level template?


These values are probabilistic and follow a Gaussian distribution. For each level (e.g., spinal_level_03.nii.gz), the sum of values across Z equals one. Since the variability of spinal level location across individuals is relatively large (i.e., large standard deviation of the Gaussian distribution along Z), each value is fairly small.

The code that generated these spinal levels is available at dev/spinal_level/
