FreeSurfer:~> tksurfer ben lh pial subject is ben hemi    is lh surface is pial surfer: current subjects dir: /home/virtualuser/apps/freesurfer/subjects surfer: not in "scripts" dir ==> using cwd for session root surfer: session root data dir ($session) set to: surfer:     /home/virtualuser Reading image info (/home/virtualuser/apps/freesurfer/subjects/ben) Reading /home/virtualuser/apps/freesurfer/subjects/ben/mri/orig.mgz surfer: Reading header info from /home/virtualuser/apps/freesurfer/subjects/ben/mri/orig.mgz surfer: vertices=136724, faces=273444 surfer: single buffered window surfer: tkoInitWindow(ben) surfer: using interface /home/virtualuser/apps/freesurfer/lib/tcl/tksurfer.tcl Reading /home/virtualuser/apps/freesurfer/lib/tcl/tkm_common.tcl Reading /home/virtualuser/apps/freesurfer/lib/tcl/tkm_wrappers.tcl Reading /home/virtualuser/apps/freesurfer/lib/tcl/fsgdfPlot.tcl Reading /home/virtualuser/apps/freesurfer/lib/tcl/tkUtils.tcl Successfully parsed tksurfer.tcl reading white matter vertex locations... % the frustration is that I never got to see the surface..since it almost took 10mins..I only see the tksurfer tools and the blank display window.
