mne_do_forward_solution ERROR

Hi,

I'm getting the following error prompt when trying to compute the forward
solution:

'No BEM surfaces found in simu-20480-20480-20480-bem-sol.fif'

Even though it took a very long time, the forward model setup completed
without novelty and I've been employing the same procedure for the last
couple of months. What could be the problem?

Thanks a lot,

Gabriel Obregon

Hi Gabriel,

the bem resolution you use is way too big (20480 vertices per interface)

you should use ico 4 for bem layers with something like:

# For homegenious volume conductor
mne_setup_forward_model --homog --surf --ico 4

# or
mne_setup_forward_model --surf --ico 4
