Hey Brainstorm forum!
I am having problems generating a BEM head model for all of my subjects’ in Brainstorm. However, computing single and multiple sphere models work just fine.
I have tried numerous ways of loading the MRI anatomy into Brainstorm to see if manipulating those variables would allow me to make a BEM model without receiving an error; but nothing has worked. Any help is much appreciated! Thanks in advance.
Whenever I attempt to create a BEM model, I get this error message:
