mne_kit2fiff
Overview
mne_kit2fiff converts KIT (Yokogawa/Ricoh) MEG data to FIFF format. KIT systems store data in .sqd or .con format, and this tool enables processing KIT data with MNE tools.
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.
Usage
mne_kit2fiff [options]
Options
| Option | Description |
|---|---|
--sqd <file> | Input KIT .sqd or .con file |
--sns <file> | Sensor layout definition file (optional) |
--hpi <file> | HPI coil positions in head coordinates (optional) |
--out <file> | Output FIFF file |
--stim <list> | Comma-separated stimulus channel indices |
--help | Print help |
--version | Print version |
Description
The tool reads KIT MEG data and converts it to FIFF format. Optionally, sensor layout information (--sns) and HPI coil positions (--hpi) can be provided for accurate coordinate transformations. Stimulus channels can be specified with --stim to be included as trigger channels in the output.
Workflow Context
This tool is the entry point for processing KIT MEG data with MNE:
- Convert KIT data →
mne_kit2fiff - Process raw data →
mne_process_raw - Continue with forward/inverse pipeline
Example
# Convert KIT data with sensor layout and HPI information
mne_kit2fiff --sqd recording.sqd --sns sensor_layout.txt --hpi hpi.txt --out recording-raw.fif
# Convert with stimulus channels
mne_kit2fiff --sqd recording.sqd --stim 160,161,162 --out recording-raw.fif
