Good afternoon, I am new to Freesurfer and following the instructions to find out the Cortical Thickness of a Volume-defined ROI(http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness), everything goes well until step 4. Even if I try to use -reshape-factor 7 as suggested, it reshapes it to 6 and so the next step gives an error because the segmentation is shaped to 7. Would anyone mind giving me some guidance on how to do it? Many thanks, Eva
