mne_brain_vision2fiff
Overview
mne_brain_vision2fiff converts BrainVision EEG data files to FIFF format. BrainVision is a widely used EEG acquisition system, and its data format consists of a header file (.vhdr), a data file (.eeg), and a marker file (.vmrk).
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.

Workflow Context
This tool is used at the beginning of a processing pipeline when the source data comes from a BrainVision EEG system:
- Convert BrainVision data →
mne_brain_vision2fiff - Process raw data →
mne_process_raw - Continue with forward/inverse pipeline
Example
# Convert BrainVision data to FIFF
mne_brain_vision2fiff --vhdr recording.vhdr --out recording-raw.fif
