[Eeglablist] LIMO: Two samples t-test from GUI - "Error using fullfile (line 103), All inputs must be strings, character vectors, or cell arrays of character vectors"

[Elisabetta Pisanu]

hmm, I see... I'm using v 3.3, I ran the two samples t-test yesterday. So,
you suggest me to use scripts or update to v3.4, right? Is this version
(3.4) stable with eeglab 2021? Sorry to ask, but I had troubles in the past
with old versions of LIMO and now I'd like to be sure that everything works
fine  :)
Thanks a lot!
