I have calculated Bivariate Granger Causality for ERFs based sources. Calculated GC between 4 ROIs that showed significance on the source space analyses. Calculated GC matrix for each subject / btw 4 ROIs

- I just want to know what is the value I obtain when exporting the connections values matrix after GC.

2)Also, does it make sense to statistically contrast those values between the two directions of connectivity (ie. scout1 to scout2 vs. scout2 to scout1)? Hence, I obtain a t-value to assure the actual direction. 12>21 for example.

Thank you very much in advance
