Hi! Was wondering if I could already delete the uploaded file that I shared. Also, thit it work?

On the other hand I tried to load that data in a Linux PC with:

raw = mne.io.read_raw_ctf(file_path, system_clock='ignore')

OUT:
ds directory : /home/usuario/Desktop/MEGEYEHS/MEGEYEHS_scripts/15909001_MatiasIson_20220530_02.ds
    res4 data read.

So now I don’t even get to read the data. I tried creating a fresh environment and reinstalling mne and the same error came up. Do you know what could be causing this?

I found this post where @mscheltienne said to try it on a fresh environment but it didn’t work in my case.
