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:

```python
----> 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](https://github.com/mne-tools/mne-python/issues/12542)).

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](https://mne.tools/stable/generated/mne.Epochs.html#mne.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!
