Dear @Francois,
Thank you for the reply. I call it atlas, but I think what I mean is parcellation/scouts (I used the following tutorial to obtain the USCBrain atlas: https://neuroimage.usc.edu/brainstorm/Tutorials/DefaultAnatomy?highlight=(uscbrain)) and it contains 130 something scouts. What is "missing" currently are the scouts.
When I try to compute scout time series for an EEG file, I get the following message:
And when I look in the anatomy tab, I can't select any scouts (everything is greyed out, see below):
While previously all scouts of the USCBrain atlas were located here.
I hope is makes some sense,
Thanks in advance!
