How do I delete a Simulink template?

11 views (last 30 days)
I created a Simulink template that I no longer wanted to show on my "Simulink Start Page" so I deleted the .sltx file. Now I am getting the following error (pretty much continuously)
Warning: An error has occurred during refresh of Action named createNewBlankModelAction.
Warning: Generator should return a DAStudio.ToolSchema.
Warning: Error reading file "C:\Users\Charlie\Documents\MATLAB\ME322_326_Blank_Model.sltx". Failed to open reader with error: Package does not exist
Do I need to do something in Simulink so that it stops looking for this template file?

I think I found the cause of the problem and a solution.
The reason this warning shows up is because MATLAB is looking for the default model template, but the file does not exist. In order to fix this you need to give it the location of a new default model template file.
Here is the code I used to fix the error on my machine. It resets the Simulink default template model to the factory version provided by MATLAB.
filename = Simulink.findTemplates('factory_default_model');

I think that might cause some issues if you are missing files unintentionally. Though you would think a total re-install would default to the factory template.

Hi guys,
I am facing the same. For now I am dealing with it with the use of warning off; command in command window. Then, it is not disturbing me ;)
It might be so that you have to run the command every time you lunch MATLAB or automate this thing in some way.

You can remove the template from Simulink start page, Navigate to template location specified in template details and delete the template .For more information about templates refer the documentation

This answer does not address the issue. Further, I'm still having this issue even after resinstalling MATLAB in its entirety. MATLAB seems to be looking for a Simulink template file even though it has been removed. The refresh action seems to occur each time something major happens in Simulink (like opening a new Simulink file or closing Simulink).
