Hi Yi Ming,
thank you for your message. I think this is unfortunately not documented but you can find it in the code: https://phabricator.mitk.org/source/mitk-diffusion/browse/master/Modules/Connectomics/Algorithms/mitkConnectomicsNetworkCreator.cpp$111 Edges are weighted by the sum of the corresponding fiber weights. In the typical case of unweighted fibers (weight=1), this defaults to the fiber count between two regions. The fiber weights are adjusted by fitting them to the data using a methdo similar to SIFT2 in the fiber processing perspective. The fiber length could theoretically be taken into account by weighting the fibers by their length, but I did not implement this weighting option.

For example, how are the length and number of fibers in a bundle related to the output edge weights? Thank you!
