Hi all,

We wanted to provide some guidance that will help us help you when Homer3 or AtlasViewer isn't working properly. 🙂

Please provide your

> MATLAB environment and version (i.e. MATLAB 2019b, MATLAB Runtime)

> Operating system (PC, Mac, Linux)

> A screenshot of the error message or bad output-- there is a log file which contains the output in the Homer3 application folder: Homer3.log

Providing a reproducible example is important so we can figure out what is going on. If the issue occurs with our fNIRS course data, it is easy for us to reproduce, but if you are having an issue with Homer3 using your data it is best for you to provide the:

> groupResults.mat file from the group folder if you have one

> A screenshot of your processing stream or its .cfg file

For both Homer3 and AtlasViewer:

> if possible, the SNIRF file/SD files that cause the problem

At the moment it is unwieldy to host files on this platform, so provide a link to a Google Drive, OneDrive or Dropbox download. 🙂

Thanks for helping us develop Homer3 and AtlasViewer!
