I had a protocol with 11 subjects' data.
I clicked File > Export subject for one subject.
The process took a long time. So I closed all windows including MATLAB.
I open Brainstorm again. All subjects' info except that subject is gone.
Under brainstorm_db > protocol name> anat or data, I can see all subjects' folders.
But they are not showing up within the Brainstorm window under the anatomy or the functional data tree.
How can I restore the protocol as it was before?
Reloading the protocol took care of it.
Sorry I didn't think of it the first time...
