Dear all,
 
I have used GAT toolbox to produce nodes and edges for BrainNet. When I load the surface, node and edge in the load file browser, the program gets stuck for ever. There is no error message that pops up however, so I am abit confused what goes wrong. When I used another node files (AAL 116) which corresponds to my edge dimension, the program works perfect, so there might be something wrong with my node file.  The only different that I notice comparing my node file with the one that Brainnet provides (AAL 116) is the number of precision after decimal (see attached file). Below comes the first three lines from my node file:
 
-38.65 -5.68 50.94 4 7.039344e+00 Precentral (L)
41.37 -8.21 52.09 4 2.941712e+00 Precentral (R)
-18.45 34.81 42.20 1 4.531071e+00 Frontal Sup (L)
 
Have I missed anything? The first three columns stands for the node dimension and the fifth column stands for the degree of node betweenness. What does the fourth column stand for?

Hi Kambiz,

Thanks for using BrainNet Viewer.

The error occured because there are blank characters in the nodal label. Replacing the blank with either '.' or '_' would solve the problem. 

I'm not sure what the fourth column stand for, maybe the module. Please see the manual of GAT to find the exact answer. 


Best,
