Has anyone tried generating EEG signals using MNE library?

I’m working on a research related to EEG data, and I want to simulate EEG signals using MNE. Is it possible?

Yes: Simulate raw data using subject anatomy — MNE 1.7.1 documentation

Hi,

There’s no option to change the number of electrodes. And its accessing a dataset to generate the signal. Can you give me more details on how I can change the parameters and alter it according to my needs?

Please start with the introductory tutorials to familiarize yourself with MNE. The number of electrodes is provided in the Info and Forward objects defined in this cell:

fname_info = meg_path / "sample_audvis_raw.fif"
info = mne.io.read_info(fname_info)
tstep = 1 / info["sfreq"]

And this cell:

fwd_fname = meg_path / "sample_audvis-meg-eeg-oct-6-fwd.fif"
fwd = mne.read_forward_solution(fwd_fname)
src = fwd["src"]

For this example sake, an MEG signal simulation is done using the Info in fname_info and the forward model in fwd_fname. In your case, you could create the Info with mne.create_info or load it from one of your EEG files; and you still have to create the forward operator for your subject (or template) anatomy.
