Hi all,

Now I have long epoch data and I want to segment it every 2 seconds.  
I know mne.make\_fixed\_length\_events can make equally-spaced Events arrays but only fit for Raw data.  
Are there any other method in MNE can do this?

Thanks for any help.

Best regards,  
Yuri

What is your ultimate goal here? There a few different solutions,  
depending on your goal and comfort in using NumPy's reshape function.

How long are your current epochs? How did you go from continuous/raw  
data to the current long epochs?

Best,
