not really migrate, although we've been moving away from tk in the newer stuff.

Are there any plans to migrate from TK to QT or WXWidgets?

Tim,

Thanks for the pointer to VirtualGL, that seems like a great solution to
some of the VNC problems we have.

I've put together a wiki page describing the tksurfer 'sliver' display
problem, and potential solutions, here:

http://surfer.nmr.mgh.harvard.edu/fswiki/TksurferDisplayProblems

Thanks to everybody on the list who has contributed potential
solutions.

I have another suggestion. When I am logged to my machine locally,
tksurfer works but only if I enable auto-redraw AND the color scale
bar. However, when I log in remotely (via FreeNX), I get the same
sliver problem described here.

I found a workaround, which is to use VirtualGL. If you can install
VirtualGL on your system, then you can run tksurfer like so:

/opt/VirtualGL/bin/vglrun tksurfer bert lh inflated

The idea of VirtualGL is to force the hardware on the server to run
the rendering commands, and then stream the resulting images to the
client, rather than forcing the client to do the rendering. Thus, I
would expect that using VirtualGL from a local session would be
exactly the same as not using it from a local session (only slower).
Strangely, tksurfer actually works better for me when I use VirtualGL,
even if I am running a local session! That is, I no longer have to
enable auto-redraw and a color scale bar to see the surface.

So if you can install VirtualGL and its dependencies on your system,
it's possible it will improve tksurfer reliability even on local
sessions. For some reason. Note that this may impose a performance
penalty, but it is not noticeable on my setup.

Abe,

This tksurfer display problem has been a difficult one to debug, due to
the complexity of opengl and graphics drivers, and the lack of error
codes (at least that I can find).

Sebastian mentions some possible workarounds in his email.  The first
one to try, assuming you have an Nvidia graphics card, is to update the
driver.  To do this:

su root
/sbin/init 3
/usr/bin/nividia-installer --update

(follow the instructions)

often times this update fixes the tksurfer 'sliver' problem.  outside
of
that, you can try overriding the mesa drivers.  you'll need to talk to
your sysadmin to do that.

Subject: [Freesurfer] tksurfer




Hello,





I?m trying to view and check the smoothing and inflation surfaces, the
white and pial surfaces for ?bert? using tksurfer as I?m trying to get
used to using Freesurfer, but I?m a little confused to what I?m
seeing. When I type in: ?tksurfer bert lh inflated? for example, I
only see a very small section at the very end of the image?is this
correct? When I view the curv files, I do see a green pattern overlaid
on the inflated surface, however it?s still so small. When I view the
pial and white surfaces, again, the section displayed is very small, I
don?t know if this is correct or if this is what I am supposed to be
seeing? Also, when I type in: ?tksurfer bert lh sphere?, I see nothing
at all.





If someone could shed some light on the matter I?d be extremely
grateful.





Thank you
