Create 3-Layer BEM model from prepared flash MRI images.

subject : str

Subject name.

overwrite : bool

Write over existing .surf files in bem folder.

show : bool

Show surfaces to visually inspect all three BEM surfaces (recommended).

subjects_dir : string, or None

Path to SUBJECTS_DIR if it is not set in the environment.

This program assumes that FreeSurfer is installed and sourced properly.

This function extracts the BEM surfaces (outer skull, inner skull, and outer skin) from multiecho FLASH MRI data with spin angles of 5 and 30 degrees, in mgz format.
