When I run tksurfer, only portions of the cuneus, lateral occipital, and superior parietal regions are displayed. This occurs in both FS versions 4.2.0 and 4.4.0. I am using a 32 bit BU Linux system which is equivalent to redhat 5.0.
The error message is similar to those in previous posts, but previous suggestions don't seem to help.
