Dear Bruce and the Freesurfers,
I had to update my ATI graphics driver and set the doublebufferflag to 1.

Everything is working just fine.

Thanks for your help.
Michelle

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

Thanks for helping.

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.

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.

           nope, nothing else should be

           "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.
