Hi Alfonso,
I can live with duplicates. It makes sense that if I select all rois in the graph explorer I will get both region A to region B and Region B to Region A in the output table . However, not all the ROIs are duplicated (see 381-89) and not all of the ROIs have the same calculated FDR values (see 188 to 146 and the same connection 146 to 188). 

188 146 -3.99 0.0001 0.0419
146 188 -3.99 0.0001 0.0399
271 68 -3.96 0.0001 0.0476
68 271 -3.96 0.0001 0.0476
381 89 -3.94 0.0001 0.0064

I am using conn 17a. I have enclosed two new screen shots. Why would 381 to 89 be significant but not 89 to 381?

all the very best,
Jen
