Edge size
Hi, after nbs, we receive a matrix and wrote an edge and node file. Displaying the results works fine. However, the results are fwe corrected p-values. This means that the lowest value describes the most significant edge. If we display the results, brainnetviewer defines the size by value, so that the highest (and most insignificant result) becomes the thickest edge.

How can we invert this behavior so brainnetviewer correctly displays the findings?

Best & thanks, Lucius

RE: Edge size
Hi, the p value matrix can be transformed inversely: -log(p), before being loaded in brainnet viewer.
