1) Could you indicate to me if TBSS analysis is recommended for longitudinal study of DTI parameters ?I have looked at the FSL mailing and noticed that similar things have been asking as "longitudinal TBSS", but all these questions were based only on two time-points per subject.Dear FSL's experts,I have one group and three time-points per subject and would like to assess the evolution according time-points of DTI parameters (FA, MD, ...).
2) And if this is the case, which steps of TBSS tutorial should I follow and which steps should I personalize in my particular case of three time-points ?
3) Concerning the statistical analysis, how should I proceed in terms of inputs and models of the longitudinal three time-points ?
Many thanks in advance for helping !!Best regards,Matthieu
