[Mne_analysis] reading bem solution

[Tadeusz W. Kononowicz]

Hello Mne Users,


This code works fine:
bem1 = path + '-20480-20480-20480-bem-sol.fif'
surfaces = mne.read_bem_surfaces(bem1)

But when I want to read another solution I got that. Any hints?


bem2 = path + '-5120-5120-5120-bem-sol.fif'
surfaces = mne.read_bem_surfaces(bem2)
