Hi @BEGINRX ,
I would like to work on this issue. Have you tried any other export formats, or does the error only happen with fmt="edf"? Also, could you share the exact error message to understand the problem better?

Thanks!

Hi. I have tried other formats like "brainvision" and "eeglab". The files were exported successfully. Yes, the error only happened in edf. The error messages are only the ones listed above. There is no more information. May I send you the raw file? Or you can download from the website https://physionet.org/content/sleep-edfx/1.0.0/sleep-cassette/#files-panel
