Hi every body

In analyzing of functional connectivity with correlation method, I saved the output in Excel format.

as we can see the matrix of coefficients is symmetric, **what is the difference between positive and negative coefficients in coefficients?**

For example, node (1, b) and node (A, 2) in the second image have the value -0.9. node (1 , c) and node (a , 3) have the value +0.89.

Can you give additional information about the type of connectivity (directional or nondirectional) in the correlation method ??

best regards
