Diagram of the connectometry analysis process. The diffusion MRI (dMRI) data from all subjects are reconstructed in MNI space through Q-space diffeomorphic reconstruction. Then the spin distribution functions are calculated from the data and compared to the predicted local fiber directions from the atlas to create a connectome matrix. A quantitative anisotropy (QA) map is calculated based on the local connectome matrix. Tractography is performed along the voxels that show QA change correlations with spaceflight.
