How to concatenate epochs with different lengths and/or time

Thanks for your answer Alex.

Here’s what I did to solve my problem. Maybe the solution could help other people.

  • Export MNE epochs as numpy array using epochs_trial.get_data
  • Use numpy.concatenate to concatenate them. That function enables concatenation with arrays of different lengths.
  • Create a new MNE epoch with the numpy array using mne.EpochsArray.
