FIF — Elekta/MNE Native
Format Overview
FIF is the Neuromag / Elekta MEG vendor format and the MNE-Python
canonical file format. Most MEG labs and many EEG labs using MNE export
FIF.
Loader
Primary: mne.io.read_raw_fif(path, preload=True).
Common Pitfalls
- Maxfilter applied vs not. Check
info["proc_history"]; raw MEG vs
tSSS-processed are different.
- File splitting. Long recordings split into
*.fif, *-1.fif, ...;
MNE handles via the link annotations.
- EEG-in-FIF gotcha. Some labs save EEG-only as FIF; channel naming
remains "EEG NNN" instead of 10-20.
EasyBCI Path
