Jon,

Here are my findings.

-If I ssh from Mac to Linux everything works as expecting, meaning I am running tkmedit on the remote machine but displaying it on the Mac client, and it appears as I would expect.

-If I ssh from Mac to Mac I am able to call the tkmedit command but it displays on the server side, not the client. This is definitely some issue relating to X11 (I have X11forwarding set to yes) but I just cant seem to figure it out the exact setting needed to get it to display on the client side.

Of course neither of these replicates your error... In your case the image window opens, but the image window is blank (white). If anyone one the list has experienced something similar I would interested to discover what if any remedy exists.

Hi Jon,

I myself have not been able successful running tkmedit over an ssh session using Mac as both client and server... But I know it can be done. There's a lot of factors involved, many to do with Xwindows/Xforwarding/XQuartz/ssh and have nothing to do with freesurfer. So its been a bit of a challenge to debug. Ill follow up as soon as I reasonable can.

Hmm that is a very strange error you are encountering. Im trying to duplicate the issue on my end. I only have one Mac 10.6 and one Mac 10.7 machine but Ill let you know what I find and hopefully I can come up with a solution.

Jon,

I have not seen or heard of this error before... are both machines Mac OSX 10.6.8? Also, will the same command will produce a brain image when not logged in remotely?

hi freesurfer folks

I'm ssh'ing to from one MAc to another X11 is on both machines MAC OS X 10.6.8

When I start TKmedit with: (freesurfer files are in the freesurfer directory)

tkmedit freesurfer brainmask.mgz -aux T1.mgz

I get the errors: Thu May 30 11:34:50 cerebrum.uwm.edu tkmedit.bin[78500] <Error>: kCGErrorIllegalArgument: _CGSFindSharedWindow: WID 349 Thu May 30 11:34:50 cerebrum.uwm.edu tkmedit.bin[78500] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

tkmedit GUI opens and the image window opens, but the image window is blank (white) , (no image of the brain)

i have set X11forwarding to yes in the /etc/sshd_config file so xeyes works ok remotely Jon
