Dear MNE users,
I want to make data with the size is 1 second and is shifted 0.2 second, namely, overlapping windowed data.
If I used mne.make_fixed_length_epochs(raw, duration=1,preload=Flase), I can make 1 second data, but there is no overlapping between each window. Do you know how to make overlapped data ?
Best,
Kyu
Hello @kyuwanchoi,
make_fixed_length_epochs() has an overlap parameter that should do what you want!
Best wishes,
Richard
Hi Richard, thanks for your reply.
when I checked make_fixed_length_epcohs() it does not have an overlap parameter. How can I change the input as follows for 80 % overlap? (sliding windows are shifted every 0.2 sec).
mne.make_fixed_length_epochs(raw, duration=1, preload=False)
Best,
Kyu
You need MNE-Python 0.23 to get the overlap parameter. Please see the description in the documentation I linked to.
Best,
Richard
Richard, thank you so much for your support!
First, I installed the latest mne. When I typed pip install mne. I received the reply as follows,
Requirement already satisfied: mne in c:\users\choikx4\anaconda3\envs\mne\lib\site-packages (0.23.0)
I used the command as follows,
epochs = mne.make_fixed_length_epochs(raw, duration=1, preload=False, overlap=0.8)
Then, I have got the error as follows,
TypeError: make_fixed_length_epochs() got an unexpected keyword argument ‘overlap’
What’s wrong with me?

I cannot reproduce this problem. Maybe you forgot to activate the correct conda environment, so you weren’t actually using version 0.23 at the time? Try again like this:
epochs = mne.make_fixed_length_epochs(raw, duration=1, preload=False, overlap=0.8)
and if you still get the error, do
print(mne.__version__)
to confirm that you’re in a python environment that has access to the v0.23 that you installed.
Thank you Dan, I checked the version. My version is 0.22.dev0.
How to update my version to v0.23?
