When I using the yasa.topoplot function the index MUST be the channel names (e.g. [‘C4’, ‘F4’] or [‘C4-M1’, ‘C3-M2’]). A list of the accepted montage/channel names can be found here:
https://mne.tools/stable/generated/mne.channels.make_standard_montage.html#mne.channels.make_standard_montage

What I am curious about here is that there are 7 channels in the psg data. It doesn’t work if the number of channels is different. What should I do if the actual clinical data is different? Is there a way?

Could you please share a minimal example of Python code that demonstrates the problem?

import mne

raw = mne.io.read_raw_edf('C:/Users/SC4001E0-PSG.edf', preload=True)
print(raw)
print(raw.ch_names)

chan = raw.ch_names
print("print channel :", chan)

print(raw.info['sfreq'])

raw.resample(100)
sf = raw.info['sfreq']
sf

raw.filter(0.3, 45)
data = raw.get_data() * 1e6
print(data.shape)

import pandas as pd

hypno = pd.read_csv("C:/Users/yasa_example_night_young_hypno.csv", squeeze=True)
hypno

import yasa

yasa.plot_hypnogram(hypno)
yasa.sleep_statistics(hypno, sf_hyp=1/30)
counts, probs = yasa.transition_matrix(hypno)
probs.round(3)

import numpy as np

np.diag(probs.loc[2:, 2:]).mean().round(3)

hypno_up = yasa.hypno_upsample_to_data(hypno, sf_hypno=1/30, data=raw)
print(len(hypno_up))

yasa.plot_spectrogram(data[chan.index("EEG Fpz-Cz")], sf, hypno_up)

yasa.bandpower(raw)
yasa.bandpower(raw, relative=False, bands=[(1, 9, "Slow"), (9, 30, "Fast")])
bandpower = yasa.bandpower(raw, hypno=hypno_up, include=(2, 3, 4))
bandpower.to_csv("C:/Users/bandpower.csv")
fig = yasa.topoplot(bandpower.xs(3)['Delta'])

Error —> 47 fig = yasa.topoplot(bandpower.xs(3)[‘Delta’])

Thank you, @PhD-GOAT.

As a general remark, please provide more context to your questions. We need the full traceback, for example. But also the version numbers of libraries you’re using etc.

That said, I’m not familiar with yasa, and I suggest you ask the author of this package for advice.

Best,
Richard

hi, @richard

Vallat who made yasa told me to ask mne about the channel!
