Hi Bruce,
When I use the -t flag, I get this message in the output:
mghRead(1057/mri/lh.gwratio.mgh, -1): could not open file
I tried:
mris_anatomical_stats -t 1057/mri/lh.gwratio.mgh 1057 lh

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

I am trying to get an output with average gray/white ratio values for each
segmentation. I tried using the gwratio.mgh file as the input for
mris_anatomical_stats, but got the following error message:

Any insight?
