[Eeglablist] Error in ICLabel feature extraction

[Hamza Imtiaz]

Yes, certainly. I've uploaded the dataset and the script to the sccn/eeglab GitHub.

Dear Hamza,

Would you creating an issue and uploading a dataset. It might be because you have a non integer sampling rate.

All of this is done in the EEGLAB environment and the filetype is .edf. I've tried updating EEGLAB to the latest version (2023.0) and have reinstalled the plugin as well. Attached below are the error message and the code snippet.
