Homer3 is available at GitHub at here.  This is the latest installment in the HOMER software series for analyzing fNIRS data. It builds upon Homer2 by enabling custom processing scripts at the session and group levels. This will enable more powerful statistical analyses of session and group level results. Homer3 also implements the Shared NIR data Format (SNIRF) that has been developed and adopted by a broad consortium of software and hardware developers. Please join the Homer google group discussion forum here.

We also offer Homer Premium access for Homer3 users, with this premium access you can have additional materials and functionality.

In Homer Premium package:

High-Resolution Fluence Profiles

High-resolution precomputed sensitivity data. This enables access to higher fidelity fluence data without requiring the computational investment of performing local fluence simulations.

Training Materials
you can access video recordings of fNIRS training courses. Materials include lectures with a strong emphasis on data analysis exercises using the Homer3 software, as well as ongoing webinars.

Please Register as Homer Premium Member to get access to all above materials.


After 10 years of developing the Homer2 and AtlasViewer toolboxes (2009 to 2019), Homer2 is now being replaced by Homer3. AtlasViewer will continue to evolve along with Homer3. Homer2 will remain available online. It is unlikely that any more revisions will be made to Homer2.
