Is there a way to abort the running of startup scripts in Simulink Project based on a condition check ?

I have a few scripts set as startup shortcuts in a Simulink Project. Whenever you open a Simulink Project all the startup scripts are run .However I need to know a way to abort the loading of the Simulink Project and close it in case a condition check fails in the startup script.

Hi @Kritika Bhowmik,

I understand that you want a way to abort the loading of the Simulink Project and close it in case a condition check fails in the startup script.

Simulink Project executes all startup shortcuts after the ‘openProject’ command is executed to open a project in MATLAB. So normally the project is already opened by the time your script runs.

However, you can use the ‘if-else’ loop and ‘close’ function inside your startup script to close a project as soon as some condition fails.

Here is a sample code snippet for your reference:

% Inside your startup script: 
% Perform your condition check first 
if ~your_condition 
    % Access the currently loaded project 
    proj = currentProject; 
    % Display a message 
    warning('Condition failed. Closing project.'); 
    % Close the project immediately 
    close(proj); 
    % (Optionally) you can error here if you want: 
    % error('Aborting due to failed condition.'); 
    % After closing, you might want to return immediately 
    return; 
End 
% If condition passes, the script simply continues 

You may refer to the following documentation links for more details:
