Dear all,

I have two connectivity matrices (32 channel EEG) holding average phase lag indices of Condition A (pre) and Condition B (post) and I aim to compare them using the network based statistics toolbox (NBS). The concatenated connectivity matrix has the dimension 32x32x2. I also loaded the node coordinates. However I have trouble understanding the design matrix. What does the matrix need to look like if I want to obtain the statistical differences between both matrices? I tried some example but I always get the error: "Design matrix not found or inconsistent". I hope you can help me!

Best,

T.
