External Email - Use Caution Hi Bruce, thank you for your quick answer. I managed it now to create cannot files based on the atlas volumetric segmentations. I first created: mri_vol2surf —src .../Hammers_mith_atlas_n30r83_SPM5.nii --out .../Hammers_AVG.nii --out_type mgh --he

Hi Boris vol2surf samples a scalar overlay in the volume to be a scalar overlay on the surface. This is NOT the same as a surface itself - it contains no geometry or topology information. Try giving freeview a surface (which I guess you have for subject 0021). Something like freeview -f \ 00

Those are the commands. Can you send the command lines you used and a fuller description of exactly how it is not working? On 1/25/19 10:56 AM, Boris Rauchmann wrote: External Email - Use Caution Dear FreeSurfer Developers, I´m trying to extract the cortical thickness of individuals fro
