While running simulation on cortical surfaces we need to calculate geodesic distance as opposed to euclidean distance due to the shape of the cortical surface. The virtual brain uses geodesic_library for this calculation. The library implements the original paper in C++. The original source code can be found in Google Code Archive: https://code.google.com/archive/p/geodesic. tvb_geodesic repository implements a cython wrapper on top of the C++ code which then is released to Pypi (tvb-gdist) and conda-forge (Tvb Gdist).

However, the code is now outdated and users have reported various issues. In this project, we aim to update the code and fix those issues.
