[Mne_analysis] question

[Emanuela Liaci]

Hi again,

since with the mat file it was more complicated that I imagine, I created
now a text file which contains the number of the channel, theta and phi
(here attached).

When I run this:
montage=mne.channels.read_montage('easycapM23',ch_names=channel_names,
path="/Users/Emanuela1/Desktop/ICA/easycapM23.txt", unit='cm',
transform=False)


I get always this error: OSError: [Errno 20] Not a directory:
 '/Users/Emanuela1/Desktop/ICA/easycapM23.txt'

But I actually could upload other text files from the same folder for other
purposes. why do I have this problem?

Many thanks,
Emanuela
