% X is a 3D group tensor
% [time,region x region,subject]=size(X)
%   dimensions 2 and 3 are symmetric, dimension 4 is subjects, and dimension 1 is time
% OutTens is the unfolded and stacked triu of X for each subject; it is 4D!

[~,~,ss]=size(X);

for loop1=1:ss
    OutTens(:,:,:,loop1)=dcp_mat2tens(X(:,:,loop1));
