create BEM surfaces using the FreeSurfer watershed algorithm for MEG

correct outcome should include bem folder with resulting files and also
watershed subfolder with resulting files. In case of the error above the files in bem
folder are missing and there are files only in watershed subfolder.</div><div>FreeSurfer 6.0.0, Ubuntu, MNE 19.0.0 <br></div><div>Thank you in advance.</div><div>Sincerely yours,</div><div>Kirill</div></div>
