Hi Siobhan -- no clue. If you can share your data along with a script that
is no longer than 15 lines, I could perhaps try to help debug. It's hard to
guess what could have gone wrong from two lines of code.

Thanks Mainak,
Sorry I probably should have shown the code I was using. Below is the code
I am using - I do specify the channel accordingly. I have had a play around
with the different options in plot_image? and I get exactly the same graph
when I remove combine = ?mean? and have no inputs to plot_image.
ecg_epochs = mne.preprocessing.create_ecg_epochs(eeg_data, event_id=999,
ch_name = 'EKG')
ecg_epochs.plot_image(combine='mean')
Is there anything else you think it could be?
Thanks for your help!
Siobhan

It doesn?t look like the ECG channel is being used because in the log it
says:
?combining channels using ?mean??
You can use the ch_name argument to provide the channel or alternatively
set the channel type using raw.set_channel_types

Hi All,
I am new to MNE and am having some issues with identifying ECG artifacts,
I have gone through the relevant tutorials and examples, but when I run the
code the ?ecg_epochs? image does not look how I would expect it to. I am
using the mne.preprocessing.create_ecg_epochs function. Please see the
image below. I have also tried the mne.preprocessing.find_ecg_events
functions to no avail
Can anyone please point me to what I am doing incorrectly! I have checked
the ECG channel, and it has very well defined PQRS waves, so I don?t think
it is an issue with that channel.
Thanks,
Siobhan O?Brien
