Problems loading g.tec .mat file

Dear Francois,

I have two versions of the EEG data set. One is the post processed data in .mat format, which is not in gtec format and I could not import it in the brainstorm.
I also have the raw EEG data in the .eeg and .vhdr format. I tried to import the raw data and I get this error:matlab_error

I would really appreciate if you help me import either of these files.

Best regards,
Sima.
