[Mne_analysis] Mne_analysis Digest, Vol 75, Issue 1

[Mauricio Aspé Sánchez]

Hi!
Thanks for your answers.

Efectively I set "eog = True".
Would I have to set, when I read the raw edt, n_eeg to another value
instead of None?
Currently I'm doing that by

raw = read_raw_edf(input_fname = bdf_file, n_eeg = None, stim_channel = -1,
annot = None, annotmap = None, hpts = hpts_file, preload = False, verbose =
None)

On the other hand, I cannot find the documentation for mne.rename_channels.
Could you tell me what do I have to do, more specifically, with this
function?

All the best,
Mauricio.
