Hello,

I am a new freesurfer user. I tried to view subject data with tkmedit for the first time after the recon-all process finished without errors. Here is what I typed and the message I got:

[ariana:~/Desktop/ELISSA_
THESIS/ATO] cmurphy% tkmedit ATO brainmask.mgz -aux T1.mgz -surfs -aseg
Wed Oct 16 14:35:57 ariana.local tkmedit.bin[66069] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
xp_init: error: not initialized
error: invalid CoreGraphics connection
Abort


Can someone explain this error message? Despite that the recon-all log said that the subject was completed without error, there were several places in the log that read invalid. Is this normal?


Also, I realized that I have an older version of freesurfer and should upgrade. Should I delete the former version and re-install with new version?

Thank you for your help,
E
