[Eeglablist] Append External EMG channel to EEG

Can you import your EMG data with eeglab successfully? Do the events have the same latencies?
You could try something like this:
1) import EMG data in eeglab
2) rename to store in memory:
emg_data = EEG.data; emg_event = EEG.event;
3) without clearing memory, import EEG data
4) check that event latencies correspond anencephaly correct if necessary (emg data as well if there is a delay)
5) merge by creating a 65th channel containing EMG data:
EEG.data(65,:) = emg_data;
Let me know if that works or not.

Both the system received the same TTL trigger simultaneously. How can I add the EMG channel to the EEG dataset and sync it using the triggers?
