Hi,
I am trying to generate FA-weighted structural connectivity from two self-defined ROIs. When I ran the following command the streamline counts can be generated without issue:
tck2connectome -symmetric -zero_diagonal tracks_10M.tck parcellation.mif parcellation.csv
But when I tried the following, it gave an error saying one of the region was not assigned any streamlines:
tcksample tracks_10M.tck fa.mif mean_FA_per_streamline.csv -stat_tck mean
tck2connectome tracks_10M.tck parcellation.mif mean_FA_connectome.csv -scale_file mean_FA_per_streamline.csv -stat_edge mean
I checked the registration and it looked fine.
I really appreciate any advice on how to resolve this.
Best
Xinyu
