Cannot open nedf file from Neuroelectrics

[JoaoAmaro2001]

Description of the problem

When I run:

p = r'C:\Users\joaop\pessoal\20240627111911_OE204007_EXP4.nedf'
mne.io.read_raw_nedf(p)

I get the following error: { "name": "ParseError", "message": "no element found: line 1, column 0 ()", "stack": "Traceback (most recent call last):

File c:\Users\joaop\Anaconda3\envs\data_science\Lib\xml\etree\ElementTree.py:1713 in close self.parser.Parse(b\"\", True) # end of data

ExpatError: no element found: line 1, column 0

During handling of the above exception, another exception occurred:

Hello! 👋 Thanks for opening your first issue here! ❤️ We will try to get back to you soon. 🚴

@JoaoAmaro2001 can you check to see if you can load the data in other software? And is your file version 1.3 or newer (the reader docs say these are the supported versions)?

[JoaoAmaro2001]

Hello @larsoner, I have tried using neuroelectrics' plugin for EEGLAB and I also get an error. I have checked the .nedf file and the version is 1.4.

If other software also falls, it suggests that the file is corrupt. I'll close but let us know if you manage to read the file using something else. Maybe it didn't copy from one system / drive to another?
