Importing data from fNIRS devices

MNE includes various functions and utilities for reading NIRS data and optode locations.

NIRx (directory)

NIRx recordings can be read in using mne.io.read_raw_nirx(). The NIRx device stores data directly to a directory with multiple file types, MNE extracts the appropriate information from each file.

SNIRF (.snirf)

Data stored in the SNIRF format can be read in using mne.io.read_raw_snirf().

Warning

The SNIRF format has provisions for many different types of NIRS recordings. MNE currently only supports continuous wave data stored in the .snirf format.

Storing of optode locations

NIRs devices consist of light sources and light detectors. A channel is formed by source-detector pairs. MNE stores the location of the channels, sources, and detectors.

Warning

Information about device light wavelength is stored in channel names. Manual modification of channel names is not recommended.
