HI Anastasia,

I'm new to tracula.  I was able to get the stats of each diffusion parameter for each tract, as shown below.  However, when I try and use waypoint in freeview to display the mean paths, using the command here:

freeview -w /data/bil-mb2/fMRI/CAST/all_freesurfer_subjectsdir/stats/*.path.mean.txt ------------------------------------------------------------------------
I get the below error.  Please let me know if you have any ideas as to what could be wrong here. 

Thanks very much.

Karuna
