Hello @Faidou and welcome to the forum!

The Biomag Demo scripts apparently expect an environment variable named USER to be set, see the config.py script:

http://mne.tools/mne-biomag-group-demo/auto_scripts/library/config.html#sphx-glr-auto-scripts-library-config-py

You can set it in config.py e.g. by adding the line

os.environ['USER'] = 'Faidou'

after the import statements.

You may also wish to check out the MNE-BIDS-Pipeline as an alternative that is under active development.

Best wishes,
Richard
