ROI on connectivity measures

[Raymundo.Cassani]

Hi @tourette95, check this post:

Parametric t-test : Independant, cannot select rows for connectivity [NxN] result

The issue seems to be that you are specifying Signal names or indices to compute the test. This is not possible with NxN connectivity matrices, as each element of the adjacent matrix is identified with two channel names (e.g. A×B). Is this your case? Please share the parameters (screenshot of the process GUI) used compute the PLV matrices, as well as the parameters for the t-test
