Dear FSL experts we have run probtrackx2_gpu with the --network option to generate connectivity matrices among the 90 regions of the AAL atlas. we then recognized that there are a lot of identical numbers of streamlines in the matrices. This number is always the largest number in the matrix (i.e. 1.67772e+07) and it is equal (apart from the fact that there are only 5 decimals in the scientific notation of the number of streamlines in the generated connectivity matrix) to 2^24. it seems that the maximal number of streamlines is truncated to 2^24! we are wondering whether this problem is related to probtrackx2_gpu or to parameters of our terminal / Ubuntu OS. how to solve this problem? Thanks in advance for any advice.
