Hello all,

I am a student working on a project to build pre-processing code sets for an fNIRS instrument from G.tec company. I am stuck in the step of converting fNIRs data in "*.mat" file into "*.snirf" file.

The raw data logged in the “*.mat” file contains the continuous wave data and the time. The montage is same to the one here:

I contact the technician in the G.tec company. But they don’t have the conversion library that can convert fNIRs data in "*.mat" file into "*.snirf" file.

Here is the link of the shared fNIRs raw data in “*.mat” file. The fNIRs data are from the first to sixteenth rows.

Does anyone know how to convert “*.mat” files into “.snirf” format? 

Thanks a lot.
