Hi Mingrui, 

When manually loading surfaces and nodes, BrainNet performed great and generated the image I needed. But when I tried using the same surface/node file and saved option, there was this Index exceeds matrix dimensions error.  

Below is the error reported in Matlab.

I've also tried updating to your August post with the code BrainNetViewer_20170403u_code.zip but with no luck.

Any suggestions? And thanks for your help!

Index exceeds matrix dimensions.
