Try typing

time redraw

At the tcl % prompt. Something sounds like it is very wrong as it should be less than a second, not a minute. You aren't running over vnc or something, are you?

Dear Bruce and the Freesurfers,

It turns out that the hemisphere does rotate, but only if I press the same button again after at least a minute or so. Then I have to wait for a while before I can press another rotation button. Do I maybe need to do any display setup for using hardware acceleration under Ubuntu?

Thanks.
Michelle

nope, nothing else should be required. Did you push any "rotate" buttons first?

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
