[Mne_analysis] No BEM surfaces found

Hi Alan, 
 
There is an example about how to process the face data using mne_python. 
Please see the link, 
https://martinos.org/mne/stable/auto_examples/datasets/plot_spm_faces_dataset.html
for your reference. 
I do not try it.

Hello, 
I’m trying to run mne_do_forward_model on the SPM dataset. I get the following error

aleggitt at cerebrum:~$ mne_do_forward_solution --meas /data/users/alanData/SPM-face/MEG/SPM_CTF_MEG_example_faces1_3D.fif --mri /data/users/alanData/SPM-face/subjects/SPM/mri/T1-neuromag/sets/COR.fif --bem /data/users/alanData/SPM-face/subjects/SPM/bem/SPM-20480-20480-20480-bem.fif

Setting up the BEM model using /data/users/alanData/SPM-face/subjects/SPM/bem/SPM-20480-20480-20480-bem-sol.fif...

Loading surfaces...
No BEM surfaces found in /data/users/alanData/SPM-face/subjects/SPM/bem/SPM-20480-20480-20480-bem-sol.fif
Forward computation failed (see above)

Prior to running this, I’ve successfully run the following commands 

mne_setup_mri
mne_watershed_bem
mne_setup_foward_model --surf

mne_setup_source_space

Am I missing a step or do I need to modify my options for mne_do_forward_model?
Thanks,
Alan
