[Mne_analysis] Assistance regarding montage

[Paul Fishback]

        External Email - Use Caution        

Hello,

I'm not sure whether this is the appropriate forum, but I think some of my
MNE questions are a bit too specialized for stackoverflow.

I have an EEG file I've read in and I wish to create and plot a montage,
whose coordinates I've created manually. Everything works fine until the
last line, where I try to plot the montage, and I'm not sure of the source
of my problem:

import mne as mn
#channel coordinates expressed as list of points in R^3 with z=0.
channel_coords=[(-.25,.7,0),(.25,.7,0),(-.27,.35,0),(.27,.35,0),(-.32,0,0),(.32,0,0),(-.3,-.35,0),(.3,-.35,0),(-.22,-.7,0),(.22,-.7,0),

(-.6,.43,0),(.6,.43,0),(-.73,0,0),(.73,0,0),(-.6,-.43,0),(.6,-.43,0),

(0,.32,0),(0,0,0),(0,-.32,0),(-.9,0,0),(.9,0,0),(-.5,0,0),(.5,0,0)]
directory='/Users/fishbacp/Jupyter December 2019/Phase 1 EEG Data/11.edf'
raw = mn.io.read_raw_edf(directory, preload=True)
channels=raw.info["ch_names"]
#I know which particular channels I wish to drop.
bad_channels=['E', 'LIO', 'RIO', 'X1', 'X2', 'X3', 'X4', 'X5', 'X6', 'X7',
'X8', 'X9', 'X10', 'X11', 'O2%', 'HR', 'DC03', 'DC04', 'EEG Mark1', 'EEG
Mark2', 'BP1', 'BP2','Events/Markers']
raw_temp=raw.copy()
raw_temp.drop_channels(bad_channels)
channels=raw_temp.info["ch_names"]
print(len(channels))
print(len(channel_coords))
ch={channels[i]:channel_coords[i] for i in range(len(channels))}
montage=mn.channels.make_dig_montage(ch)
mn.viz.plot_montage(montage)

The last line of my error message reads AttributeError: 'tuple' object has
no attribute 'copy'

Thanks for any help spotting my error.
