Hi Mingrui,

I am trying to do a similar thing, but I get the following error on Matlab:

Index exceeds matrix dimensions.

Error in BrainNet>DrawSphere (line 2708)
set(Node,'FaceColor',EC.nod.CM(ci,:));
Error in BrainNet>PlotNode1 (line 2014)
DrawSphere(surf,j,2,1,EC);
Error in BrainNet>FileView (line 3610)
a=PlotNode1(surf,a,2,EC);
Error in BrainNet>LoadFile_ClickedCallback (line 4754)
a=FileView;
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in BrainNet (line 53)
gui_mainfcn(gui_State, varargin{:});
Error in @(hObject,eventdata)BrainNet('LoadFile_ClickedCallback',hObject,eventdata,guidata(hObject))
Error while evaluating PushTool ClickedCallback

The matrix I entered was 57*3:

[0.88 0.04 0.04; 0.88 0.07 0.07; 0.88 0.11 0.11; 0.88 0.14 0.14; 0.88 0.18 0.18; 0.88 0.21 0.21; 0.88 0.25 0.25; 0.88 0.28 0.28; 0.88 0.32 0.32; 0.88 0.35 0.35; 0.88 0.39 0.39; 0.88 0.42 0.42; 0.88 0.46 0.46; 0.88 0.49 0.49; 0.88 0.53 0.53; 0.88 0.56 0.56; 0.88 0.6 0.6; 0.88 0.64 0.64; 0.88 0.67 0.67; 0.88 0.71 0.71; 0.88 0.74 0.74; 0.88 0.78 0.78; 0.88 0.81 0.81; 0.88 0.85 0.85; 0.88 0.88 0.88; 0.88 0.92 0.92; 0.88 0.95 0.95; 0.88 0.99 0.99; 1 1 1; 0.99 0.99 1; 0.95 0.95 1; 0.92 0.92 1; 0.88 0.88 1; 0.85 0.85 1; 0.81 0.81 1; 0.78 0.78 1; 0.74 0.74 1; 0.71 0.71 1; 0.67 0.67 1; 0.64 0.64 1; 0.6 0.6 1; 0.56 0.56 1; 0.53 0.53 1; 0.49 0.49 1; 0.46 0.46 1; 0.42 0.42 1; 0.39 0.39 1; 0.35 0.35 1; 0.32 0.32 1; 0.28 0.28 1; 0.25 0.25 1; 0.21 0.21 1; 0.18 0.18 1; 0.14 0.14 1; 0.11 0.11 1; 0.07 0.07 1; 0.04 0.04 1]

Please advise?
Thank you!

This feels like a stupid question, but I can't find any documentation on what format the .txt file is supposed to be for this. I'm using the new version, so the custom colormap is no longer just a pop up, but a popup looking for a .txt file. I've tried a line for each module in a txt file with "module# RGB" and "RGB Module#". Neither work. There doesn't seem to be a user manual for the newest version and the old one doesn't mention this custom colormap button or functionality. 

Can anyone point me in the right direction with this? I'm trying to not change each module's color by hand. Thanks!

Hi, 

Thanks for your feedback. Here, I attached an example of a custom color txt file. It includes a 6x3 matrix like this:

1 0 0
0 1 0
0 0 1
1 1 0
1 0 1
0 1 1

where each row corresponds to a color of a module (e.g., "1 0 0" are the R, G, and B values, and this color is red). 

I also attached a color displayed in the panel after reading this file. We will revise the manual to clarify its format.

Hope this would be helpful. 

Best,
Mingrui
