How can I access the original .mat files from the BCI Competition IV datasets?

Hi everyone,

I’m currently working with MNE and trying to use datasets from the BCI Competition IV, specifically the ones like BNCI2014001(MOAB). I understand that MNE can work with the .gdf files, but for compatibility with some benchmarking tools (like MOABB or custom MATLAB code), I would need the original .mat versions of the data.
I’m already working on a project that relies on these .mat files, so being able to access them is critical for continuing my analysis.
Unfortunately, the official TU Graz servers (lampx.tugraz.at / bnci-horizon-2020.eu) appear to be down or unreachable.
Is there any alternative mirror, official archive, or way to retrieve the original .mat files?

Thanks in advance for any suggestions!

Best regards,
Beatriz

The BCNI Horizon 2020 website works for me, I just tried downloading a record from the first data set:

Is there any particular data set that you need and that isn’t available?

Hello! Thank you for your response.
Following your reply, I tried accessing the server again, this time using a VPN in the UK, and it worked — quite slowly, but it did manage to download the files. I dont know why it is not working directly from Brasil.
I appreciate your help, and thank you for keeping these resources available.

Best regards,
Beatriz
