Hi @Abdullah Alhassan, I understand you are getting errors like ‘Unrecognized function’, ‘Reference to non-existent field’ and some with ‘.fig’ and ‘.m’ file. Here’s how to fix the errors in your MATLAB GUI

Your GUI is trying to use functions like ‘z_CreateFcn’ and ‘y_CreateFcn’ that aren't defined. Make sure you define all the callback functions for your GUI components, like sliders and buttons
The code is trying to access a field ‘AnzahlNachbarn’ that doesn't exist in ‘handles’. Make sure all fields are initialized in ‘handles’, usually in the ‘OpeningFcn’ or ‘initialize_gui’.

Below is example of ‘OpeningFcn’ and ‘initialize_gui’ with necessary comments.

function myGui_OpeningFcn(hObject, eventdata, handles, varargin)
    % This function is executed before the GUI is made visible.
    
    % Initialize the handles structure
    handles.output = hObject;
    
    % Initialize custom data fields
    handles.metricdata.AnzahlNachbarn = 0; % Example field
    handles.metricdata.SomeOtherField = 1; % Another example field
    
    % Update handles structure
    guidata(hObject, handles);
    
    % Call the initialize_gui function to set up the GUI
    initialize_gui(hObject, handles);
end

function initialize_gui(hObject, handles)
    % This function sets up the initial state of the GUI components.
    
    % Initialize GUI components, e.g., set default values for controls
    set(handles.slider1, 'Value', 0.5); % Example of setting a slider value
    set(handles.editText, 'String', 'Default Text'); % Example of setting text
    
    % Ensure that all necessary fields in handles are initialized
    handles.metricdata.AnzahlNachbarn = 5;
    handles.metricdata.SomeOtherField = 10;
    
    % Update handles structure
    guidata(hObject, handles);
end

3. Initialize all needed variables and fields in the ‘OpeningFcn’ or a setup function to prevent errors.
