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

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

      When you type in a different angle make sure you hit return. Tk
      is strange that way

      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
