my name is Tyler Farren and I am from the Carnegie Mellon University Psychology Department.  I recently installed FreeSurfer on a cluster and it seemed to install properly.  However, when I attempt to go through the steps on the testing page, nothing seems to work.  I am running CentOS 6.2. I get the following errors:

$ freeview -v $SUBJECTS_DIR/bert/mri/norm.mgz -v $SUBJECTS_DIR/bert/mri/aseg.mgz:colormap=lut:opacity=0.2 -f $SUBJECTS_DIR/bert/surf/lh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/rh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/lh.pial:annot=aparc:edgecolor=red -f $SUBJECTS_DIR/bert/surf/rh.pial:annot=aparc:edgecolor=red
