how to read my own nirs file with MNE?

[shijian97]

I installed mne and mne-nirs, and I have some nirs file like "1.nirs"
I use raw_intensity = mne.io.read_raw_nirx('1.nirs', verbose=True), and there is OSError: Need a directory for fname but found a file at ".......\1.nirs".
Can you help me how to read my nirs file? and I want to use function mne.preprocessing.nirs.scalp_coupling_index with the raw data.

What device/software was used to record the data? Did you read through https://mne.tools/dev/auto_tutorials/io/30_reading_fnirs_data.html?

If your file is from another vendor (e.g., Hitachi, SNIRF, etc.), use the matching function:

SNIRF: mne.io.read_raw_snirf('file.snirf')

Hitachi: mne.io.read_raw_hitachi('file.csv')
