<p>Hello,</p>
<p><br>
</p>
<p>I'm messaging because I recieved the error "<span class="ansi-red-intense-fg ansi-bold" style="font-family:Cambria,serif"><span style="font-family:Cambria,serif">RuntimeError</span></span><span style="font-family:Cambria,serif">: Digitization points not
in head coordinates, contact mne-python developers</span>" while trying to bring up a topography plot using
</p>
<p><em>plot_projs_topomap()</em>. Some background: I have some eeg data that has already been preprocessed in eeglab which I would like to load into MNE. I managed to load just the eeg data into MNE using
</p>
<p><em>mne.io.read_epochs_eeglab()</em>. However, it seems that<em> read_epochs_eeglab()</em> ignores the location data stored in the eeglab EEG file structure. I assume this is becuase the function only cares about extracting the "raw" data from the .set file?<br>
</p>
<p><br>
</p>
<p>Below is my code which calls the data stored in the attached zip file:</p>

<p>I'm pretty new to MNE and the concept of montages as a filetype confuses me. But if you have any pointers/could advise me what exactly I've done wrong I'd really appreciate it.</p>

<p>All the best,</p>
