Spinal Cord ccf

Hello, 

Appreciate your work on `ccf-2017`. We are currently calibrating the spinal cord data. We would like to know if you have the ccf file of the spinal cord data. For example, similar to `http://download.alleninstitute.org/informatics-archive/current-release/mouse_ccf/annotation/ccf_2017/annotation_25.nrrd` Is there an nrrd file about the spinal cord?

Waiting for your patient reply :)
