They are not random, they are 20% of the maximum value. If you want to generate 
stats at a different threshold, you can find the dmri_pathstats command line in 
trac-all.log and add the --pthr option (the default 20% would be --pthr .2).

In the visualization step of Tracula processing, freeview -tv 
merged_avg33_mni_bbr shows some tracts with very high threshold (i.e. 171), 
which make them look like the reconstruction-failed ones.
The tracts failed to reconstruction usually show threshold of 300 (not 
changeable) with tiny rounded cylinder shape.
In successfully reconstructed tracts with very high threshold, it looks ok, 
when I adjust threshold to the similar value from contralateral one.

Is there any reason for this extremely high threshold? or it’s just randomly 
set values?

Bests,
J.
