When opening the .set file, using the code below
import mne
raw = mne.io.read_raw_eeglab('s01_051017m.set')
the compiler return an error
IsADirectoryError: [Errno 21] Is a directory: 's01_051017m.set'
May I know how to solve this issue.
The .set file is accessible via the following link: https://ndownloader.figshare.com/files/14242478
Appreciate for any help
you passed the folder name and not the file to the read_raw_eeglab
I tested and it works fine

Hi @agramfort , thanks for the clarification.
I changed the following and now it works.
raw = mne.io.read_raw_eeglab('s01_051017m.set/s01_051017m.set')
print(raw.annotations)
outputted:
Reading s01_051017m.set/s01_051017m.fdt
<Annotations | 597 segments: 251 (95), 252 (104), 253 (199), 254 (199)>
But within the folder s01_051017m.set, there are two files, .fdt and .set
s01_051017m.set
-s01_051017m.fdt
-s01_051017m
I am curios on how to open the .fdt file, or does the above amended code open the .fdt simultaneously?
I read the documentation on read_raw_eeglab, and it mentioned
input_fname
strPath to the .set file. If the data is stored in a separate .fdt file, it is expected to be in the same folder as the .set file
However, I’m not so clear whether .fdt is open simultaneously.
I assume, the .fdt contained the time series signal.
Sorry, this is my first time work with .set file.
Based on the discussion.
Fdt is not matlab file. It’s a companion file to a .set file that is actually a .mat file
Hence,
import mne
raw = mne.io.read_raw_eeglab('s01_051017m.set/s01_051017m.set')
raw.plot(start=5, duration=5)
will produce the following graph
This confirmed that, the read_raw_eeglab load the .fdt simultaneously.
Yes, you always pass the .set file, and MNE will auto-detect if there is an additional .fdt file.
