Hey!

I’m attempting to remove some bad segments I annotated using mne.Annotations().  
Unfortunately, my code removes the entire epoch rather than the annotation itself…

Is there a way around this?

I’m linking the github to my notebook below.

I’d value any assistance

I think your problem is that you are trying to epoch your data to the `bad_segment` annotation start times. `mne.Epochs` by default will drop any epochs that contain an annotation that starts with `BAD_`.

If you don’t have any other event markers but would like to epoch your data (excluding bad segments), I think what you are looking for is [make\_fixed\_length\_epochs](https://mne.tools/dev/generated/mne.make_fixed_length_epochs.html)
