I am trying to work with a .vhdr file from brainvision. I loaded the data, and did some plots. Then, I tried the ICA, but I ended up with the following error: "No digitization points found". I'm guessing this is related to the set montage. I did a lot of searching, and I noticed a lot of people have the same issue. Still, I can't seem to find a way to solve this.  I am also attaching the file, in case you need. For now, I just want to be able to run the ICA and to properly do the set the montage (if needed). I looked all over the MNE website for solutions, but I simply can't work this out.

PS: MNE is amazing!

Here is what I've got so far:

import mne

fname = "go.nogo.01.vhdr"
raw = mne.io.read_raw_brainvision(fname, preload=True)

raw.plot_psd(fmax = 50)




raw_new_ref = mne.add_reference_channels(raw, ref_channels=['RightEar'])

ica = mne.preprocessing.ICA(n_components=15, random_state=97)
