Please also read doc\elastic_graph_data_structure.pdf to understand the EG data structure.

Brain Artery Data

The orignal data could be downloaded here. The data is stored in point cloud. We converted it into EG format and cut it into four components: top, bottom, left, right as mentioned in the paper. The processed data could be downloaded here.
