Your data was probably mapped to fsaverage when you call the preproc or surf2surf commands? If so you should specify fsaverage as the subject nane. Best Martin

Dear FreeSurfer guys,
I am using longitudinal processing stream and with the RepeatedMeasuresAnova. I follow the instruction here from http://surfer.nmr.mgh.harvard.edu/fswiki/RepeatedMeasuresAnova
my fsgd file is:
GroupDescriptorFile 1 Title k_longitudinal Class k Variables TP1-vs-TP2 TP1-vs-TP3 Input k_1 k 1 1 Input k_2 k -1 0 Input k_3 k 0 -1
contrasts is:
tp1-vs-tp2.mtx tp1-vs-tp3.mtx tp2-vs-tp3.mtx tp-effect.mtx mean.mtx 0 1 0 0 0 1 0 -1 1 0 1 0 1 0 0 0 0 1
I run the mris_preproc and mri_surf2surf commands as the same for left hemi thickness,
but when I run the mri_glmfit command it reports "ERROR: you must use '--surface subject hemi' with surface data". if i add the flag as: mri_glmfit ...(as the same before)... --surface k lh or --surface k lh thickness or --surface k_1.long.k lh or --surface k_1.long.k lh thickness or --surface k_1 lh or --surface k_1 lh thickness it still goes wrong and even not make an output folder.
Any problems there?
thanks, Kaiming
