Hi Hari,

I understand that you are facing issues during the neural network training process. The error message provided indicates that there is an issue with handling a GUI event in the MATLAB environment, specifically related to a “GridLayoutController”. The error message points to an unrecognized field name “ContentAreaPosition”, which suggests that the code is trying to access a property or field that does not exist in the specified context.

This kind of error could be due to custom user interface code that is not correctly handling properties of layout objects.

Here are some steps to troubleshoot and resolve this issue:

• Review Custom UI Code: If written custom UI code, review it to ensure that it is correctly using the properties of the layout objects. For example, make sure that “ContentAreaPosition” is a valid field for the object one is accessing.
• Isolate the Issue: Try to isolate the part of the code that triggers the error. This can be done by commenting out parts of the code or creating a minimal example that still produces the error.

As a workaround, try to temporarily disable the part of the code that is causing the error, if it is not critical to the main functionality one requires, and see if the rest of the application works as expected. However, this is not a long-term solution and should only be used to bypass the issue temporarily while working on a proper fix.

Please refer to the following MATLAB Documentation links for the correct usage of the layout properties and event handling and make sure that the code follows the guidelines provided in the documentation.

• https://www.mathworks.com/help/matlab/ref/matlab.ui.container.gridlayout-properties.html?searchHighlight=layout%20properties&s_tid=srchtitle_support_results_2_layout%20properties
• https://www.mathworks.com/help/deeplearning/ref/trainnetwork.html?searchHighlight=TRAINNETWORK&s_tid=srchtitle_support_results_1_TRAINNETWORK

Hope it helps!

Best regards,
