Homer3 is the latest installment in the HOMER software series. It builds upon Homer2 by enabling custom processing scripts at subject and group levels. This will enable more powerful statistical analyses of these results 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 subscribe to the Homer3 community forum here on openfnirs.org! We are grateful to all of the Developers who have contributed to Homer and AtlasViewer over the years.
Please see the wikis for Homer3 and AtlasViewer to find documentation to guide you in using each software package. Training courses and webinars are available with data sets and exercises to help you better learn Homer3 and Atlasviewer.
Please use the Homer forum to ask questions and start discussions about the software.

Homer2
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.
Access to the open-source Homer2 and AtlasViewer software can be found at homer-fnirs.org.
