color of nodes and edges

Hi

I have just started using Brainnet viewer for structural analyses and would like to change the color of the nodes and edges.
For example, for one brain image I would like to color the edges and nodes blue, but for another image, I would like to color them in red.

Whatever I do, Brainnet viewer always goes to red as primary color.
I have tried to change the color in the node file to 5 (for all nodes), but it still only provides me with a red option.

Any suggestions on how I can change this?

Many thanks
Heidi

Hi Mingrui,

I am encountering the same issue (I am trying to change the nodes to black). I tried to right click the color square but this I get the following error:

Any help would be appreciated, thanks.

RE: color of nodes and edges

Hi Edward,

Would you please try the latest version of BNV? We have changed all the color square to button, and just click it to change colors.

Best,
Mingrui

RE: color of nodes and edges

Hi Mingrui, thanks for the reply. Sorry for the delay from my end- just saw this today.

I am using BrainNet Viewer version 1.63 (20181219). The error message I pasted actually shows up when I try to use the button you described to change colors.

I've looked into it more and it seems like a Matlab uisetcolor issue rather than a BrainNet issue. I'll try and test the solutions below, and if they don't work, I'll give you an update here.

I can confirm that this was indeed the issue (a Matlab rather than a BrainNet issue). Thanks for all your hard work making this program.
