Manually dropping bad epochs

[Hugues1273 (Hugues)]

Dear all,

I would like to drop bad epochs from my epochs data. Therefore, I create Epochs:

Epochs = mne.Epochs(RawData_Notched, events = Events_from_annot, tmin = Tmin, tmax = Tmax, baseline = None, preload = True, event_id = {"Stimulus/S 5": 5, "Stimulus/S 10": 10, "Stimulus/S 14": 14})

Then I plot the epochs and I left click on the epochs I want to remove:
Epochs.plot()

Then I remove the visually selected epochs:
Epochs.drop(True, reason = "bads")

Then I plot again the Epochs and selected Epochs indeed seems to have been removed
Epochs.plot()

However, when I want to get the indices of the removed Epochs, bads is empty:
Epochs.info

returns

<Info | 9 non-empty values
 bads: []
 ch_names: Fp1, F3, F7, FT9, FC5, FC1, C3, T7, TP9, CP5, CP1, Pz, P3, P7, ...
 chs: 64 EEG, 1 ECG
 custom_ref_applied: True
 dig: 67 items (3 Cardinal, 64 EEG)
 highpass: 0.5 Hz
 lowpass: 100.0 Hz
 meas_date: 2024-03-09 10:54:44 UTC
 nchan: 65
 projs: []
 sfreq: 500.0 Hz
>Dropped 0 epochs: 
The following epochs were marked as bad and are dropped:
[]
Channels marked as bad:
none

What is wrong? I would like to get the indices of the visually removed Epochs in the bad list to save them because it is important to stay transparent at each step, but I can’t, the bad list is empty…

I am using Spyder 5.5.1 and python 3.12, and I am using Windows.

Thank you so much for your help!!

Hello, when you click on epochs to mark them as bad and then close the plot, the selected epochs are automatically removed.

I think they should be available in epochs.drop_log (BTW, I recommend to name your epochs object epochs instead of Epochs).

Ok!! Thank you very much! I did not know! I will try! Otherwise I will write manually the epochs I remove.
Thank you so much for your time and your help!

Best,
