Dear Freesurfers,
I have recently installed Freesurfer 5.1 and FSL 4.1.4 on a linux machine.  When I run tksurfer, I can't rotate the hemisphere.  It will show the curvature, but the hemisphere just won't turn.  I was able to do this through virtual box on my windows laptop.

Is there another software package/toolbox that is needed?  Is either Matlab or AFNI required as well?

Thanks.
Michelle
