Can anyone shed some light on this? Thanks!

This is because you do not have the Matlab signal processing toolbox installed. However, the function should use alternative methods. What does this command return on your machine?

usepwelch = license('checkout','Signal_Toolbox')

And apologies for replying so late. You replied to your own message which led us to believe that your concern had been addressed by someone from our team.

Hi, I've run into the same issue EEGLab error in function spectcomp() at line 941. Here is what it says in the Maltab command window... C:\Program Files\MATLAB\R2020a\toolbox\stats\stats\finv.m Pop_spectopo: finding data discontinuities Selecting the first 15.0% of data for analysis...

I tried running usepwelch = license('checkout','Signal_Toolbox') and I received usepwlch = 1 as the return.

Hello, I also got stuck in this issue, and tried your method from #119, but I cannot find the path to signal processing toolbox. After running usepwelch = license('checkout','Signal_Toolbox') , I still got usepwlch = 1. Thanks.

This is because it is available on your network but you cannot check it out (someone else is using it).
