Hello FreeSurfers, I want to compare cortical thickness differences between my two groups. Is this the correct pipeline?
I ran make_average_subject on each group. To get the study thickness file in control space, I did this: mri_surf2surf --srcsubject study --srcsurfval study/surf/lh.thickness --trgsubject control --trgsurfval control/surf/study.thickness.mgh --hemi lh And then to calculate the differences, I used: mris_thickness_diff -out diff.mgh control/surf/pial control/surf/lh.thickness control/surf/pial control/surf/study.thickness.mgh. Is this the right way to do this? mris_thickness_diff says it should only be used on the same subject. mris_diff says it is still being tested. I also see mris_thickness_comparison. Which command is the best to use to get a thickness difference map? Thank you very much, Jeff Sadino
