Dear Saad
thanks for your response. I increased the number of streamlines per seed (option -P from 5000 to 6000) and again, the largest value is 2^24. With -P 6000, more connections now show this value compared with -P 5000, i.e. 98 out of 8010 connections
in the matrix have a value of 2^24 and no connection showed a larger streamline count.
Thanks in advance for any advice.
Best regards
Jürgen
Hi
That seems unlikely. If you increase the number of streamlines per seed, does that maximum also increase?
Cheers

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.
Best regards
Jürgen
