Hi Anastasia, I started recently using Tracula to do tractography for my DTI data. I did the analysis exactly as mentioned in wiki. The problem is that when I am repeating the third step (trac-all -path -c ) for the same subjects to generate the statistics; Tracula is updating all the information mentioned in the file "pathstats.overal.txt" regarding the tract's volume and the tract's metrics values. Every time the output is different. I think we have a problem in the scripts or something like this?
Attached are three "pathstats.overal.txt" files for the same subject after three consecutive runs for the "trac-all -path -c" (the same subject) Looking forward for your support Thanks
