Complete test case with real data.

Description of feature

For now, primarily due to the runners' memory limit, we only test cases using -stub, which does not run the actual modules. We would need to implement real test for pediatric/infant data for each profile tracking/connectomics/segmentation.

To do list:

• Test case for tracking.
• Test case for connectomics.
• Test case for segmentation.
