I'd like to have a general discussion on applying common spatial patterns  
on resting eeg.

I have the following questions:

Is CSP used on resting state eeg data at all? Does it have discriminative  
capacity over such data as much as it does in event-based eeg data?

If CSP can be applied to resting eeg, what is the correct way to use CSP on  
resting eeg data in a binary setting ? Can someone outline some pseudocode  
using the mne.decomposition.csp module for this scenario. (I had posted  
some of my code already on this forum. )

Thank you

you need 2 conditions to learn CSP filters.

what would they be on rest?

Sure. The two are two different forms of progression of a neurodegenerative  
disease (milder and more aggressive) on a sample of some N patients.

Is it possible at all to use CSP successfully with this data ? I have since  
tried many ways of serving this data to the CSP routine in MNE with little  
success.

I have tried concatenating rawarrays like mentioned in this example:  
[https://mne.tools/stable/auto\_examples/decoding/plot\_decoding\_csp\_eeg.html](https://mne.tools/stable/auto_examples/decoding/plot_decoding_csp_eeg.html).

Perhaps, it will be of great help if another such example is given for  
rest EEG of 2 different conditions on different patients.
