Hi,
I'm using ROI masks (spectroscopy voxels) to get cortical thickness values. I'm pretty much following the tutorial online ('VolumeRoiCorticalThickness') as I'm quite new to Freesurfer. It looks like Freesurfer has a maximum of cortical thickness ceiling at 5 mm, and I'm getting that as the maximum cortical thickness for a fair number of subject's ROI. I'd really like to hear thoughts on this: if it might be indicative of some error happening and if my mean or range cortical thickness is going to be thrown off by it?
Thanks for your help, Kari
