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 ??
