[Eeglablist] [EXTERNAL] Re: Difficulty installing Biosig after EEGLAB install on Mscbook

Wed Feb 22 11:08:42 PST 2023

Hello - 

We continue to have this problem getting Biosig installed on Macbooks - two different machines at this point. Both are fresh, new installs of Matlab (v. R2022b) and the full EEGlab version (not from github) of 2020.0 (28.8 MB). When we try to import edf files using Biosig for the first time in eeglab, we cannot autoinstall Biosig as has worked on my work PC. We have attempted to manually install Biosig with experienced Matlab users from our university, and we continue to get this error message. They suggest there may be missing files from our version of eeglab. I have submitted Issues in both eeglab and biosig Githubs but I'm also asking here if anyone knows what may be causing this problem.

Thanks,

Andi

Dear Andi,

I wish I had a solution for you, but this is puzzling.
What is sure is that if you have a computer where BIOSIG or EEGLAB works, you can copy it on a USB key and then uncompress it on the Mac, which should work. I use Mac myself. 
For the network issues, it could be an old version of MATLAB (these do not handle HTTPS secure connection well).
I hope that helps.

Cheers,

Arno

I have a student I’m onboarding to be a research assistant who uses a Macbook, and we have installed Matlab and EEGLab successfully on her machine, as well as the frontal asymmetry toolbox, using the Add On manager in Matlab. (This actually went very smoothly compared to installs on my PC!) EEGLab opens fine on the Macbook and we have since tried to open an EDF file using the Biosig tools option. EEGLAB then attempts to download and install Biosig (which on my machine has always gone smoothly). However, my student keeps getting this message:

The error message occurs regardless of what wireless network she is on, whether at home or at the university. We have checked the permissions of Matlab folder to ensure she can modify it, that’s fine. Is this problem particular to the Mac OS? How do we get this running?
