Hi Alec

it is really impossible to tell from these images and from the lack of detail in your description. Did you just tesselate the surface of the aseg? We would need you to upload the tarred and gzipped subject dir and tell us coordinate of the voxels you think are incorrect.

External Email - Use Caution

Hello,I'm a computer science student interested in 3D printing a model of my brain. I've successfully used freesurfer to create STL files of both my cortical and sub-cortical regions. Everything looks good except for some non-symmetrical excess mass below my cerebellum on my sub-cortical file. I'm certainly no neurologist, but it doesn't look quite right to me. I would appreciate it if someone would point out I can correct this, I am certainly willing to provide any needed files. Thanks, Alec Siegel
