Dear Anastasia,
Thank you very much for your help.
I have done a TBSS group analysis in FSL and I would like to do a similar study
using Freesurfer. I understood I can use TRACULA for a similar TBSS study. Is
this right? Or I should better use the dt_recon? I would like to compare my
results from FSl with th eone from Freesurfer: TRACULA or dt_recon method.
Please advise.
Many thanks,
Antonella

1. Currently trac-all uses only the MNI template, not CVS. So yes, all
steps apply.
2. See the tracula tutorial, section "outputs from tracula", to see where
to find the MNI-space outputs.
3. What clusters are you talking about? Do you want to do a voxel-based
analysis? If so, why are you using tracula? Go through the tracula
tutorial and read the tracula paper below to understand what tracula
does:
