Multiple Error Message when Plotting ERP Waveforms

[soitsybitsy]

Hello! Apologies if this is not the forum to ask this question, but I'm trying to plot ERP waveforms on Matlab2025b (Mac), erplab11.02, for my dataset, but when I set everything in the GUI for plotting ERP wavforms and click run, I get multiple error messages:

This doesn't occur when I'm running on a different computer (PC) which uses a previous version of matlab and I believe also a different version of ERPlab.

Any insights and help would be appreciated thank you!

Hello, thanks for the detailed description of the error.

It appears this stems from changes in the way the 2025 MATLAB versions handle user interfaces, which has unfortunately broken some of ERPLAB's functionality. We are looking into what to do about this, and monitoring to see whether whether issues with backward compatibility will be addressed in future MATLAB versions (e.g. some issues were fixed between 2025a and 2025b, but not all of them).

At this moment, I think the quickest fix for your issue would be to not use MATLAB 2025a or 2025b with ERPLAB. If possible, try using MATLAB 2024b and see if this fixes your issue (or any version of MATLAB between 2020a and 2024b).

Thank you for reporting this! Please let us know if this error persists while using an earlier version of MATLAB.

Thank you so much Kurt!

Hi, I also get the same error when I want to plot ERP Waveforms and ERP scalp maps. Currently, I am using Matlab2026 (laptop) and erplab12.20.

Please any help T^T

Hello! Thanks for letting us know this issue is also present in the MATLAB 2026a prerelease.

For now, the solution would be for you to use MATLAB version 2024b (or any version of MATLAB between 2020a and 2024b) - see my previous comment on this thread.

It is on our todo list to migrate away from the older user interfaces which are deprecated in newer MATLAB versions. But this will take some time before it is completed so for now the immediate fix is to use MATLAB 2024 with ERPLAB.
