Hi Lindsay
it might be easiest to do what you want in matlab. We do supply m-files
for i/o of our various formats
cheers

External Email - Use Caution
Hello Freesurfer Community,
I am wondering if it is possible to recalculate cortical thickness metrics
(perhaps using
mri_segstats or aparcstats2table) while including either a SD threshold or an
exclusion mask.
Using mri_surf2surf to register scans to the same space and then
mri_surface_stats to create the std
maps I have been comparing the variability of cortical thickness across the
cortex for multiple
scans across the same subject. From this I can determine a SD threshold point
(0.5 say) or create a
mask that includes all regions above that threshold.
I would like to use this to threshold the regions showing the highest
variability out of my
calculations for mean hemispheric thickness and also regional thickness.
Is there a way to use an SD threshold within mri_segstats or aparcstats2table?
Otherwise apply a
mask image to exclude specific vertices?
Thank you in advance,
Lindsay
