Check BEM Surfaces

Set up your Freesurfer environment.

Set SUBJECTS_DIR to your MRI directory.

Load an MRI image:

tkmedit YourSubject T1.mgz

Choose "File -> Load Main Surface", then "Browse". Go to the "bem" sub-directory (you are in "surf").

Choose a surface, e.g. "inner_skull-5120.surf", then "OK".

The surface should be shown on the MRI image. Use for example "Slice" to navigate.
