Dear community,

I failed to view scalp connectivity of 19 channel EEG electrodes as I encountered the following error:

.....................
Attempted to access surf.sphere(:,5); index out of bounds because size(surf.sphere)=[1,4].

Error in BrainNet_Option>Initialization (line 327)
if EC.lbl_threshold>max(surf.sphere(:,5))||EC.lbl_threshold
Error in BrainNet_Option_BrainNet_Option_OpeningFcn (line 79)

I appreciate your suggestions to sort it out.

Thank you.

I have used the following channel file as nodes.

Hi, the node file is not well prepared, please see the attached file and the manual.

Dear Xia,

I tried to load the file you sent to me but the co-ordinates of the scalp EEG are not fitted which resulted as below (file attached).

How can I plot 19 channel scalp EEG functional connectivity using BrainNet?

Thank you.
