Hello all, I'm doing a training comparison (training type A vs. type B), and I created thickness difference files (the rate files from the long_mris_slopes command) for each subject. How can I conduct an FSGD analysis with these thickness difference files? I tried replacing all of the lh.thickness and rh.thickness files with the lh.long.thickness-rate files, but it gives me the following error: MRISreadBinaryCurvature: incompatible vertex number in file /Applications/freesurfer/subjects/7107-60_base/surf/lh.thickness ERROR: reading curvature file
