Hi Alex,

If the there is volume geometry information in the surface header, freeview will display the surface in that coordinate. Otherwise it will display it in surfaceRAS. The center of the view is automatically set as the center of FOV of the surface.

Hi,

When using Freeview to load a surface file without volume, how does Freeview set the initial view center and cursor position? I’ve checked mid point of xyz ranges, centroid of vertices, and median. None of these gives me the initial SurfaceRAS values when opening the surface with Freeview.

Thank you!
