Hi and thank you very much for your availability.
Now, I'm running tracula as following:
trac-all -prep -c /Applications/freesurfer/subjects/subject_prova/CON_01
my CON_01 forder contains: data.nii.gz (DWI), bvals and bvecs (as used in
previous FSL analysis) and T1-images.nii.gz. File.niii.gz
Hi Stefano - The argument of the -c option is a configuration file, not a
directory. For more info on trac-all and setting up the configuration
file, please see the trac-all wiki page:
