Hi Miguel, As Bruce said, the best thing to do is to make sure you have enabled "Hardware Drivers" for your video card and make sure they are up-to-date. However, if you do not have a video card with the appropriate level of OpenGL support for an application (e.g., if you are running in a VM)

You should select a surface file to load first, such as lh.white. Then from the control panel on the left, load lh.thickness as Overlay. You can load everything from command-line at once: freeview -v orig.mgz -f lh.white:overlay=lh.thickness Best, Ruopeng On 01/13/2010 03:01 PM, Gonzalo Rojas
