Dear Freesurfer team,
I encountered a visualization error with tkregister-sess after trying to look at the
overlays of my 1st level analysis in a standard fMRI block designed localizer.
tkregister loads without errors (menu plus window) but only very faint and small colored dots are visible, no inflated hemisphere as a surface no significant overlay of the contrast, nothing.
It might seem like a specific problem with my setup, because from another computer in the lab the surface is visible (but no overlay).
*Here is the terminal output during tkregiter-sess:*
-bash-3.2$ tksurfer-sess -s NC211pre/ -analysis face.object.sm5.lh -c face-vs-object
