This page will provide links to software developed for use in fNIRS imaging. Please contact us with any additions or changes.


fNIRSOFT is stand-alone software to process, analyze and visualize functional near infrared (fNIR) spectroscopy signals through a graphical user interface and/or scripting (for automation), distributed by BIOPAC Systems, Inc. and developed by fNIR Devices.


fOSA is a software package for the processing and analysis of functional neuroimaging data using Near Infrared Spectroscopy (NIRS). The software description and operation manual is provided in the package. The current version of the software is 2.2.


HOMER2 has a GUI interface similar to HOMER1, but now more easily supports group analyses and re-configuration of the processing stream. Further, it enables users to integrate their own algorithms into the processing stream. Underneath the GUI, all of the processing functions can be accessed at the script level, adding additional flexibility. Users are encouraged to contribute their own scripts for public dissemination within HOMER2.


NAP is a MATLAB-based analysis package developed and custom-tailored for analysis of NIRS data, either through a GUI or through the command line. It enables signal denoising and GLM analysis, as well as anatomical registration of the measurements. NAP enables the analysis of entire data sets with a few button clicks.

Neuroimaging Tools and Resource Center

The Neuroimaging Tools and Resource Center is a large repository of tools and resources serving the broad neuroimaging community.


NIRS-SPM is an SPM5- and MATLAB-based software package for statistical analysis of near-infrared spectroscopy (NIRS) signals. It was developed at the Bio Imaging Signal Processing (BISP) lab at KAIST in Korea.


A suite of analysis packages is offered by NIRx.


Platform for Optical Topography Analysis Tools (POTATo) is a platform software for Optical Topography data analysis on MATLAB(r). Hitachi has been developing the platform software with the aim of providing a GUI-based workbench for researchers to explore data analysis methods and share Analysis Recipes with other researchers.

SNIRF – Shared NIRS Data Format

SNIRF is designed by the community in an effort to facilitate sharing and analysis of NIRS data.

Spatial Registration Tools for NIRS

The Functional Brain Science Lab at Jichi Medical University is dedicated to the technical development of spatial registration for NIRS. A variety of tools are described on the lab’s website.
