Details

To view electrodes implanted in multiple subjects, it's highly recommended to view them in a template space The detail mapping method is discussed in function freesurfer_brain.

To map to a template space, one idea is to find someone whose brain is normal. In our case, the choice is subject `N27`, also known as `Colin 27`. function download_N27 provides a simple and easy way to download a partial version from the Internet.

If you have any other ideas about template brain, you can use function set_default_template(subject_code, template_dir) to redirect to your choice. If your template brain is a `Zip` file on the Internet, we provide function download_template_subject to automatically install it.
