Hi,
I have another question about preparing design for longitudinal DTI study. I have controls and patients both separated to two group, those who underwent intervention and those who not.
So I suppose that I should run paired T-test for each subgroup separately, should I prepare matrix also for DTI in FEAT or should I calculate differences in Fsl maths and then create one 4D files in Fsl merge and then run 1-sample t-test????
And I also want to ask how to prepare design for longitudinal study with additional covariate...can I just add additional EV to paired T-test prepaired in FEAT???
Many thanks for your answer
Best regards
Alena
