I am trying to do a paired t-test (N=6 pairs) and when I try to
estimate, I get the following error. Is this a result of not having
enough subjects (degrees of freedom) or something else?
??? Output argument "V" (and maybe others) not assigned during call to
"/Applications/MATLAB74/spm5/spm_reml.m (spm_reml)".
Error in ==> spm_reml at 32
try, N; catch, N = 1; end
Error in ==> spm_spm at 907
[V,h] = spm_reml(Cy,xX.X,xVi.Vi);

??? Error using ==> SPM = spm_spm;
