why do i get 'off', 'Octave:ab​breviated-​property-m​atch' error warning in eeglab?

Answer 1

The fact that you reached line 202 presumably means you are in an Octave environment, not a MATLAB environment. (I'm guessing that that code is using this ismatlab function.)

That's not a MATLAB error, and is presumably an Octave error. The error message you are getting suggests that there is no longer an Octave warning labeled "Octave:abbreviated-property-match".

Perhaps do an internet search on that string?

Maybe you set

ismatlab = false

somewhere, but started in a MATLAB environment ?
