(Answer) (Category) FreeSurfer Faq-O-Matic : (Category) Troubleshooting :
In tkmedit and/or tksurfer, Save and Go To Point don't seem to work.
Make sure that the $subject/tmp directory is writeable. The point is written to the file $subject/tmp/edit.dat and if the program can't rewrite this file, the function won't work.

If your subject name is bert:

cd $SUBJECTS_DIR/bert/
chmod u+rw tmp

Now make sure you can write a file:

cd tmp
touch foo

If you get a Permission denied error, for some reason this directory is still unwritable. Ask somebody with UNIX experience to take a look at it.

If it still doesn't work, you may be using data generated from an older version of Freesurfer with a new version of the viewer. This is due to a bug in the older version. Versions from before around mid 2003 will have this problem. To fix, regenerate your surfaces using the newest version of the software.
