You can use the `read_montage` function and construct an `.hpts` file. It's a four column space delimited text file with the given extension. You can set the unit parameter to 'm', 'mm', 'cm'. You can then use the `set_montage` as Marijn suggested. Each line should be as follow:</div><div><br></div><div><span class="m_7429712295591683990m_-2051271258708120932m_4414725839236070511gmail-pl-s"><span class="m_7429712295591683990m_-2051271258708120932m_4414725839236070511gmail-pl-pds"></span>eeg Fp1 -95.0 -3. -3<span class="m_7429712295591683990m_-2051271258708120932m_4414725839236070511gmail-pl-cce"></span></span></div><div><br></div><div>The other solution would be to construct a fif file with the digitized electrode information.
