Template connectome harmonics for FreeSurfer template cortical surfaces using Gibbs Tractography Dataset

The folder contains connectome harmonics for template surface meshes cvs_avg35_inMNI152, fsaverage45 and fsaverage5 from Freesurfer, using the Gibbs connectome tractography streamlines.
The connectome harmonics framework is integrated to the SCRIPTS pipeline, and the files present here use default parameters from Table 1 in Naze et al. 2020.

Each .mat file include:
- graph Laplacian (L)
- connectome harmonics (H)
- connectome harmonics projected in the Desikan-Killiany atlas (H_DSK)
- local connectivity adjacency matrix (A_local)
- long-range connectivity adjacency matrix (A_ctx)
- vertices and faces of the cortical surface mesh (white matter -  gray matter boundary)
- degree matrix (of combined adjacency matrices)
- eigenvalues of the eigendecomposition
- r, the ratio of local connections over all connections (local_vs_global_ratio)
- average (mu_cc) and standard deviation (sigma_cc) of the long-range connectome
- z_C, the weight threshold applied to the high resolution conectome to obtain its adjacency matrix (ta_zsc)
