[Homer-users] Data export question

[Paola Pinti]

Hi Filiz,

did you run the block average and then the grand average?
The file groupresult.mat contains the average across all the subjects. If you have empty variables it means that you didn't use the block average function.
If you want to take a look at the filtered signals, you have to import the .nirs file of each subject into your matlab workspace. 
All the variables you are interested in are in the struct procResult.

I hope it will help you.

After filtering I end up with  groupresults.mat file in the same folder as the .nirs file. When I open this file in Matlab, I can see the variables such as dodAvg, dcAvg, dcAvgStd but all of these variables are empty. Can someone walk me through steps so that I can see what I'm missing. What I do is:
