- mne.io.read_raw_nirx(fname, saturated='annotate', preload=False, verbose=None)¶
Reader for a NIRX fNIRS recording.
Path to the NIRX data folder or header file.
Replace saturated segments of data with NaNs, can be:
The measured data is returned, even if it contains measurements while the amplifier was saturated.
The returned data will contain NaNs during time segments when the amplifier was saturated.
The returned data will contain annotations specifying sections the saturate segments.
This argument will only be used if there is no .nosatflags file (only if a NIRSport device is used and saturation occurred).
New in version 0.24.
- preloadbool or
Preload data into memory for data manipulation and faster indexing. If True, the data will be preloaded into memory (fast, requires large amount of memory). If preload is a string, preload is the file name of a memory-mapped file which is used to store the data on the hard drive (slower, requires less memory).

- rawinstance of RawNIRX
A Raw object containing NIRX data.
Documentation of attribute and methods.
This function has only been tested with NIRScout and NIRSport1 devices.
The NIRSport device can detect if the amplifier is saturated. Starting from NIRStar 14.2, those saturated values are replaced by NaNs in the standard .wlX files. The raw unmodified measured values are stored in another file called .nosatflags_wlX. As NaN values can cause unexpected behaviour with mathematical functions the default behaviour is to return the saturated data.
