can you run
mri_info /home/freesurfer4.4.0/subjects/corinna/1057/mri/lh.gwratio.mgh
and send us the output?

Hi Bruce, When I use the -t flag, I get this message in the output:

Hi Corinna,
the gwratio.mgh is a scalar field over the surface, *not* a surface (i.e. it has no topology information). Try:
mris_anatomical_stats -t lh.gwratio.mgh
and the rest as normal. Note that it will report the values as "thickness"
cheers Bruce
