Mean FA matrices for both acquisitions and the percentage of difference between them obtained using tracking-based and atlas-based approaches for scale 1. (a) and (c) Mean connectivity matrices computed using two different fiber tracking approaches: 1) deterministic (SD_Stream) and 2) probabilistic (iFOD2). (e) Mean connectivity matrices obtained using the atlas-based approach. These matrices were computed for both acquisition and the connection strength between each pair of regions is given by the mean FA value along the bundle connecting them. (b), (d) and (f) Histograms of the percentage of difference between the connectivity matrices computed for both acquisitions. Notes: Individual tractography-based matrices were masked by the binary structure of the common edges, i.e., the connections present in both test and retest data (84.71% and 89.26% connections, respectively). Similar graphs for the rest of the scales can be consulted in the supplementary material (Figures S9, S10 and S11).
