[Freesurfer] tksurfer rotation isssue

Hi Bruce and the Freesurfers, Sadly instead of .028 seconds, it takes ~60 second for a single 90 degree rotation.

Thanks for helping. Michelle

Here is the screen output:

Hi Michelle

28063 microseconds = 28milliseconds = 0.028 sec which is quite fast. Is that what you observe? Do you get any errors when you start tksurfer? Can you paste the screen output of tksurfer in an email? I'm not sure what's going on. When Nick/Krish/Ruopeng start reading email tomorrow, maybe they can help Bruce

Hi Bruce,

Pressing return after entering the angle doesn't help :-)

Still extremely slow: rotations, loading labels, and loading annotation.

Do you have any suggestions for a fix?

Thanks. Michelle

 Hi Bruce,
 I got 28063 microseconds per iteration. No, I'm not
 running remotely.
 Also, no matter what angle I choose, the rotation is
 always by 90 degrees.

 Thanks.

       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
