Error in GUI preprocessAll

[julama]

I get the following error for pre-processing-> run in the GUI:

Array indices must be positive integers or logical values.

Error in Project/preprocessAll (line 461)
                mexFolder = str(1:mexFolder(end));

Error in mainGUI>runpreprocessbutton_Callback (line 788)
    project.preprocessAll();

Error in gui_mainfcn (line 95)
        feval(varargin{:});

Error in mainGUI (line 61)
    gui_mainfcn(gui_State, varargin{:});

Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)mainGUI('runpreprocessbutton_Callback',hObject,eventdata,guidata(hObject)) 
Error while evaluating UIControl Callback.

What could be the issue?

Hi that is a problem with IClabel installation. Are you connected to the internet while running automagic?

Make sure, IClabel is in the automagic-master/matlab_scripts/eeglab14_1_2b/plugins/

Best, Dawid

Hi Dawid, thanks for your help! IClabel was not in this folder. After adding it manually I still get the same error (also restarted the application). And yes, I was always connected.

Thats strange. Are you using Automagic as a EEGlab extension (https://github.com/methlabUZH/automagic/wiki/Automagic-as-EEGLAB-extension)? What Matlab version do you have? I tested Matlab 2016b, 2018a, 2020a on OS and Linux and everything works fine.

Could you please go to automagic folder, /src/Project.m, set a breakpoint at line 452 and check, what values does ICLabelFolderIndex take? We can also habe a short zoom meeting today and check it together.

Hi, I ran into the same issue. When I set a breakpoint and investigate the ICLabelFolderIndex it is empty. Any suggestion on how this can be resolved?

I used the automagic-development version since it includes the ICLabel plugin. I'm using MATLAB version 2019b on MacOS

Hi, I can't reproduce the error on linux, mac or windows.

Is IClabel in automagic-master/matlab_scripts/eeglab14_1_2b/plugins/ ?

Maybe try run restoredefaultpath before starting Automagic GUI?
