<p>Hello MNE list,</p>
<p> </p>
<p>I am a relative beginner to MNE-Python and also to programming in general, so <br>
I apologise in advance if I have phrased my question ambiguously or incorrectly. </p>
<p> </p>
<p>My enquiry is in relation to running ICA with MNE-Python 0.9.0 in the removal of EOG artefacts. Essentially,<br>
the find_bads_eog attribute seems to be ignoring my EOG channel ('BIO001') which was acquired on a Neuromag<br>
306 system. I have tried running the script on other individual raw data files only to encounter the same issue.<br>
Please find below the code I was running and its resulting traceback error message:</p>
<p> </p>
<p>ica = ICA(n_components=0.95, method='fastica').fit(raw, decim=3, reject=reject)</p>
<p> </p>
<p>eog_epochs = create_eog_epochs(raw, tmin=-.5, tmax=.5 ,ch_name='BIO001', picks=picks)<br>
eog_inds, eog_scores = ica.find_bads_eog(eog_epochs, ch_name='BIO001')<br>
---------------------------------------------------------------------------<br>
ValueError Traceback (most recent call last)<br>
<ipython-input-18-ca3c097c7353> in <module>()<br>
----> 1 eog_inds, eog_scores = ica.find_bads_eog(eog_epochs, ch_name='BIO001')</p>
<p>ValueError: ['BIO001'] not in channel list</p>
<p><br>
Following this, I then tried running the same line of code, only without specifying the ch_name argument like so:</p>
<p> </p>
<p>eog_inds, eog_scores = ica.find_bads_eog(eog_epochs)<br>
---------------------------------------------------------------------------<br>
RuntimeError Traceback (most recent call last)<br>
<ipython-input-19-2e668d6c09d6> in <module>()<br>
----> 1 eog_inds, eog_scores = ica.find_bads_eog(eog_epochs)</p>
<p> </p>
<p>RuntimeError: EEG 61 or EEG 62 channel not found !!</p>
<p> </p>
<p>I am very confused about what is happening here because I didn't do EEG recordings -- only MEG. As for the issue<br>
with find_bads_eog, I am completely certain that all my raw data files contain an EOG channel('BIO001'). I would be very grateful for any suggestions on how to work around this problem, or how I might go about using BIO001 to remove EOG artefacts in MNE-Python
0.9.0. </p>
<p> </p>
<p>Thank you for making this thoroughly comprehensive MEEG imaging/analysis software. It’s totally my favorite.
</p>
<p> </p>
