Description

Why is this PR needed?

As part of the latest round of reviews of the blackcap paper, we need to add an additional region (MC, caudal mesopallium) to the blackcap atlas

What does this PR do?
This PR

  • adds the MC region during packaging
  • smoothes it similarly to how the previous annotations were smoothed
  • the smoothing function was made more re-useable by making it part of atlas_generations/annotation_utils.py
  • simplifies and updates the blackcap packaging script to work with the latest code
  • a one-off script to provide an equivalent ITKsnap compatible version of the atlas
  • (one tiny tweak to a mesh_utils.py logging message)

Unlike previous annotations, MC was annotated in the male atlas space (not the previous mixed atlas space) so we can't easily incorporate directly with the previous annotation combinations scripts.

I have therefore chosen to integrate the region during packaging, where we are already in the correct space.

Atlas validation functions all pass.

@simonweiler has confirmed he is happy with the new region based on the two screenshots below

The coronal section shows MC (light green) as a child region of M. The 3D view shows the root mesh, the M mesh and the MC mesh.
