Could you please attach your node file?

Hello, I'm going to draw a graph of volume mapping to surface with node (similar to the last mind map with black dots in the attachment"brainnet.PNG".  "brainnet.PNG" is the diagram I'm going to draw, there is a blue volume mapped to the surface, and the black dot is the labeled node.), but node doesn't show up althogh I did load the node file. I checked the manual but I can't find a solution, is it because the layers overlap in the wrong order or something else? Since I don't know how to read matlab scripts yet, I posted this question.
