Connectome matrix data

[danieleavitabile]

This is not an issue per se, but I am after some advice. I have downloaded data and code from NITRC website, so as to run the example presented on git, that works great.

I would like to have access, however, to some connectomic data matrix: if a mesh has n vertices, I would like to generate a (possibly sparse) n-by-n matrix of connectivity strengths from, say, vertex I to vertex J in the mesh.

Do you know if any such data, complementing the gifti data that you already indicate, is present in the NITRC website?
