[Homer-users] HRF export Error

[Jonathan Perry]

        External Email - Use Caution        

Hello Sefania,

This is likely due to your conversion script not including the SD.MeasList
variable.

You can create the variable and save it to your .nirs file, or you can look
for an updated version of the conversion script.

I know NIRx has one available if you are utilizing one of these systems,
but I am sure other systems have these available as well, I am only less
aware.

There is a video on youtube on what the SD variable consists of here
<https://www.youtube.com/watch?v=WXQXeYqEplo&t=2s>.

Keep in mind in creating the variable, it is a Matlab struct and needs to
be saved to your .nirs file.

I hope this helps!

Jonathan Perry
