If I am planning to do a longitudinal analysis, I understand that the LME Model is probably the most appropriate choice.  However, it says on the website that it is for univariate and mass-univariate analyses.  I would need a longitudinal model that can handle multivariate statistics (a longitudinal study using multi-modal imaging + covariates).  Can the LME model do this?  If not, is there another way to do this in FreeSurfer?
