Hi everyone, I’m working with concatenated EEG data using mne.concatenate_raws and have created annotations marking the start and end of each segment. After downsampling the data due to high sampling frequency (which was affecting the ICA analysis performance), I noticed that my annotations were lo…

The resample method allows you to do both at the same time. You could do something similar to this: events, event_id = mne.events_from_annotations(raw, use_rounding=False) data_ds, events_ds = raw.copy().resample(sfreq=ds_freq, events=events)

Thanks for the answer. This worked perfectly.
I tried many things but transforming the annotations to events and then downsample. Thanks
