Using compute_TFR or similar with EpochsEEGLAB

MNE version: 1.6.1
operating system: Windows 10

Hello,

I am interesting in looking at ERDS (or other ERP characteristics) in my EEG data.

The data is preprocessed (filtered, downsampled, ICA’d, events added, and epoched) in EEGLAB, and saved as a .set file.

I loaded the set file as following:

epochs = mne.read_epochs_eeglab(set_file)

and epochs looks correct (# of Events, time range, baseline are correct).

Plotting also works, but when I try to use:

epochs.compute_tfr()

I received the following:

----> 1 epochs.compute_tfr()

AttributeError: 'EpochsEEGLAB' object has no attribute 'compute_tfr'

I understand this is likely because mne.read_epochs_eeglab does not actually return an epochs class but instead EpochsEEGLAB (this has been clarified before (Be more explicit about what is returned by read_epochs_eeglab and read_epochs_kit · Issue #12542 · mne-tools/mne-python · GitHub).

I guess my question is are there existing methods to either convert my EpochsEEGLAB into a usable Epochs class, or a different way to load the .set file to allow it?

This is likely due to your version of MNE. If you look at the documentation of Epochs.compute_tfr, you’ll see New in v1.7 in the Notes section.
If you update your MNE version, you will have access to this new method, released on the 19th of April 2024.

Works! Thanks!
