<br>
your version of mne_surf2bem is too old.<br>
<br>
please try to install the latest version of mne C. Take the nightly build.<br>
The --force option was introduced much later than 2009.<br>
<br>
now I think we should fix this as mne_surf2bem should not be necessary<br>
for this operation.<br>
<br>
I opened an issue on github<br>
