Dear AFNI experts:
Is it possible to run AFNI group analysis related functions (3dttest++, 3dANOVA, 3dLMEr) using surfaces instead of volumetric data?
If so, I am interested to do a multiple regression with the following variables:
- Dependent variable = the surface.
- Independent variables/regressors = 7 physiological measures (3 main effects and 4 interaction effects).
- 4 covariates.
Could 3dLMEr may be a good approach to handle that regression?
Finally, I am interested to performed permutations and apply FWEr correction. I knew that ETAC could do something like that in t-test analysis. But, Is it possible to do something similar as ETAC does in 3dLMEr's output (also considering that I am using surfaces as dependent variable)?
If you could help me with my queries I would greatly appreciate it
Best regards,
Karel
