Reshape the exported PLV file to N*N matrix

PTE: How is the connectivity matrix stored?

Hi, I computed NxN PTE from 100 surface scouts. When I export the connectivity matrix to matlab, I don’t get a connectivity matrix, but instead a 10000x1 vector (TF). This vector can be reshaped easily to regain the connectivity matrix. However, since PTE is a directed measure of connectivity, the matrix is not mirrorsymmetric. Therefore, I would like to know the organisation of the TF vector. Is it: SeedA - TargetA SeedA - TargetB … SeedA - TargetZ SeedB - TargetA … or rather SeedA - …

How the Corr matix is saved?

Hi Junpeng, In the processes “Correlation 1xN”, “Correlation NxN” and “Correlation AxB”, the measure that is used is the same. In the NxN case, it just repeats it for all the pairs of signals, there is no covariance of the other signals involved. The results are the same as the non-diagonal values returned by the corrcoef function with only two signals in input. The full code of the function and some additional explanations are available here: Cheers, Francois
