Reading .rec EEG file

I am using MNE for my research.

I am unable to open .rec EEG file using the mne.io.read function.
Does MNE support .rec format?

I appreciate your help

Hello @blrk and welcome to the forum!

Have you tried using mne.io.read_raw_edf? I read somewhere that .rec may refer to EDF files.

Good luck,
Richard

using mne.io.read_raw_edf throws NotImplementedError: Only EDF files are supported by read_raw_edf, got rec

here is my code

import os
import mne
from google.colab import drive

drive.mount('/content/drive')
os.chdir('/content/drive/MyDrive/sleep_EDF_N/sleep_data/')
eeg_data = '/content/drive/MyDrive/sleep_EDF_N/sleep_data/sc4002e0.rec'
hyp_data = '/content/drive/MyDrive/sleep_EDF_N/sleep_data/sc4002e0.hyp'
raw_train = mne.io.read_raw_edf(eeg_data, preload=True)

NotImplementedError Traceback (most recent call last)

Can you rename the file to sc4002e0.edf and try again?
