[Freesurfer] Could you help me to extract my brain from MRI?

External Email - Use Caution

Hello. I have spent a lot of time testing different options in freesurfer to extract my brain for 3D printing but I could not get good results (like different parameters for skul removal and multiple images). I think the issue is with my image is to crappy because when I have used perfect MRI scan (now I think it could have been human sliced after dead) the brain looks perfect and I was able to 3D print it.  I attachment I am sending the comparation between results. Link to my MRI images and final STL files:  drive.google.com drive.google.com Please remove any private info if I left any. Please help me to create my own 3D model of brain.  Best regards, Adam
