Bum Seok,
The message 'Unable to create direct context rendering...This may hurt performance" may be ignored. It refers to the inability to use maximal graphics capabilities, but this is not a major problem, as tkmedit will merely redraw the screen more slowly. This is likely due to your computer's graphics driver not supporting the OpenGL Extentions (GLX). As long the screen redraws are not painfully slow, you should be able to use the tools as normal.

Dear Nick Schmansky After finish autorecon1 step, I checked skull stripping results with command below. tkmedit N3 brainmask.mgz -aux T1.mgz
Then, I always face to an error message such as 'this may hart performance'. Am I also able to ignored it?

Bum Seok,
The "Can't find the talairach xform..." message can be ignored. Recon- all will find that file by searching relative to the 'mri' directory. The message you see is a historical artifact from when the path to .xfm was hard-coded into the file.

During autorecon1, I find error message below during autorecon1, eventhough recon-all-status.log said 'recon-all finished without error ' Is it not considerable error message or important thing?
Thank you
