Fixel mask from densest fixel per voxel

I was wondering if it is possible to use existing functions to make a fixel mask with only the fixels with the highest FD in a voxel. I want to use this mask to compare only those (densest per voxel) fixels (in a specific ROI) between subjects. If yes, how? If no, any tips on making this function myself?


Not that I am aware of. If you do not shy away from C++ coding (or translation to Matlab / python), cmd/fixelcorrespondence.cpp and docs:fixel-image-directory-format should provide a good starting point.
