- MNE version: 1.0.1
- operating system: Windows 10

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](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?

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 @PhD-GOAT , just wondering if you were able to solve this issue? I am getting the same error.
