External Email - Use Caution

Hello, Fs

my freesurfer version is 6, I see others have the view button after load .annot file, But my version does not have this option.

Do I need to update the version? And I have installed fs6, can I install fs 7.1 on the same machine?

What's more, After loading the .annot file in freeview, can I reset its name, index, color through view-label?

Looking forward to your reply
