Hi everybody,  
sorry for all these newbie's questions, but I'm really interested in  
migrate all my EEGLab analysis to Mne-Python.

I'm trying to epoch my data, but the command

epochs = mne.Epochs(raw, events = events, event\_id = events\_ids,  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tmin = tmin, tmax = tmax, baseline = baseline, picks = picks,  
preload = True, reject = dict(eeg = 80e-6, eog = 150e-6))

gives me the error:

ValueError: No EOG channel found. Cannot reject based on EOG.

and I cannot figure out how to label the EOG channels in my raw structure.

How do I do that?

Thanks for all,  
Mauricio.

set :

reject = dict(eeg = 80e-6)

and it will not complain
