Thank you Douglas for your reply.

I have perforemed

surfreg --s subj1 --t fsaverage_sym --lh surfreg --s subj1--t fsaverage_sym --lh --xhemi mris_preproc --target fsaverage_sym --hemi lh --xhemi --paired-diff --srcsurfreg fsaverage_sym.sphere.reg --meas thickness --out lh.lh-rh.thickness.sm00.mgh --s subj1

for my *one* subject. as I understand "lh.lh-rh.thickness.sm00.mgh" file is the difference between the two hemisphere of my one subject (it's dimension is 163842 x 1 x 1). so I should check if these values are significantly different than zero, right?

but DOF of this vector is 0 so mri_glmfit returns "ERROR: DOF = 0". which is correct I think.

I believe I can't do this procedure for single subject. I want to check if there is thickening or thinning between two hemisphere for one subject. what should I do exactly?

Regards, Ashkan
