Dear all,

I am trying to visualise all the connections of only one single seed node. If the no of the nodes is increased above the 10 nodes the result is fine as shown in the figure (25 nodes). But I want to do the same for only 5 nodes, When I have less no of node to connect with that seed it gives me following error:

Index exceeds matrix dimensions.

Error in BrainNet>DrawLine (line 2546)
length_cyl=norm(sphere(surf.cylinder(i,2),1:3)-sphere(surf.cylinder(i,1),1:3))-sphere(surf.cylinder(i,2),7)-sphere(surf.cylinder(i,1),7);

I am also attaching the .edge and .node file, which I was using. Here, the first row represents the seed ROI.

Thanks,

Dear Tara Chand,

The edge file must contain an n*n matrix, in which n equals to the number of nodes in node file. I checked your files and I found that there are 6 nodes in your node file, but the edge file doesn't contain a 6*6 matrix. 

Best,

Dear Sir,

Thank you for your quick reply. It worked, By mistaken, there were some wrong entries in my edge file. However, I thought it contained 6*6 elements only. 

Thanks,
Tara Chand
