Shared Near Infrared Spectroscopy Format (SNIRF)
A standardized format for exchanging fNIRS data

Shared Near Infrared Spectroscopy Format (SNIRF) is designed by the community in an effort to facilitate sharing and analysis of NIRS data.

This repository stores the Shared Near Infrared Spectroscopy Format (SNIRF) on github.

The following open access publication introduces snirf to the community:

Tucker, S., Dubb, J., Kura, S., von Lühmann, A., Franke, R., Horschig, J.M., Powell, S., Oostenveld, R., Lührs, M., Delaire, É., Aghajan, Z.M., Yun, H., Yücel, M.A., Fang, Q., Huppert, T.J., Frederick, B.B., Pollonini, L., Boas, D., Luke, R., 2022. Introduction to the shared near infrared spectroscopy format. Neurophoton. 10.

Create BIDS compatible datasets

Coming soon on

The BIDS fNIRS Cloud is a tool for creating BIDS compatible datasets. The BIDS-Standard (Brain Imaging Data Structure) is a specification developed by the community to provide a simple and easy way of organizing neuroimaging and behavioral data in a standardized way.

fNIRS Glossary Project
Glossary of terms for fNIRS

The fNIRS Glossary Project is intended to develop a community-sourced glossary (i.e., useful nomenclature) of terms relating to functional near-infrared spectroscopy (fNIRS) including the paradigms of continuous-wave (CW), frequency domain (FD) and time domain (TD) NIRS and related symbols via a consensus-based methodology. The fNIRS Society invites all fNIRS researchers to join the fNIRS Glossary Project by writing definitions, commenting on existing definitions, adding alternative definitions where applicable, and suggesting relevant references.

The project can be accessed via this repository on github.

Best practices for fNIRS publications
A Neurophotonics paper by the fNIRS community

Best practices for fNIRS publications is an open access publication by the fNIRS community. It has been designed to provide guidelines to help enhance the reliability, repeatability, and traceability of reported fNIRS studies and encourage best practices throughout the community. A checklist is provided to guide authors in the preparation of their manuscripts and to assist reviewers when evaluating fNIRS papers.

IEC 80601-2-71:2015 
The international fNIRS standard

The IEC 80601-2-71:2015  is the current standard of the international electrotechnical comission for fNIRS equipent. An updated version is currently being worked on by an international committee.

It belongs to 80601 Medical electrical equipment – Part 2-71: Particular requirements for the basic safety and essential performance of functional near-infrared spectroscopy (NIRS) equipment.

“IEC 80601-2-71:2015 applies to the basic safety and essential performance of functional NIRS equipment intended to be used by themselves, or as a part of an ME system, for the production of functional NIRS equipment output for adjunctive diagnostic purposes, hereinafter referred to as ME equipment.”

ANSI Z136 Standards
Laser and optical safety

ANSI Z136 Standards define standards for safe use of lasers that are also relevant for fNIRS equipment.
