Hi, freesurferers

I am trying to execute the post installation tests as recommended at Freesurfer Wiki. Using a CentOS6 Virtual Machine (kernel 2.6.32-358.2.1.el6.x86_64) over Fedora 18 using VirtualBox 4.2.8. Freesurfer version is 5.2. Tkmedit, Tksurfer, qdec and freeview all work great. However, recon-all tests return errors. Thank you for your attention.
