Dear experts,

I have 18 ROIs and I performed probtrackx to find the probability of 
connection from each seed to all targets.
Now I am interested to know the actual number of fibers between each 
ROIs. If I understand correctly, probtrackx does not give you any 
information about the count of fibers.

Should I use deterministic tractography to obtain this information? If 
so which tool and tractography algorithm do you suggest?

Appreciate your help.
