Hi Franziska,
looks to me that for some reason it does not find the vec function which should be part of the package under ..freesurferpath/matlab/vec.m
so maybe you just need to source FreeSurfer in the shell before you start matlab (from that same shell).
Best, Martin

Hi, I am from Frankfurt, Germany and I want to use Freesurfer and matlab for the analysis of my longitudinal brain structural data. I want to use linear mixed effects modelling, however, I receive an error message when I execute [lhTh0,lhRe] = lme_mass_fit_EMinit(X,[1 2],Y,ni,lhcortex,3); in matlab. The error message says: Undefined function 'vec' for input arguments of type 'double'. Error in lme_mass_fit_init (line 117) vecD = vec(D); Error in lme_mass_fit_EMinit (line 69) [Theta1,Re1] = lme_mass_fit_init(X,Zcols,Y,ni,[],prs) I have already replaced parfor by for. However, my Matlab version is from 2011. It would be great if you could help me with that! Thanks in advance, Franziska
