Hi Doug,

There are approximately 40~45 slices of each individual's brain,
each saved as separate nifti files.
I'm trying to use FreeSurfer for the Non-uniform intensity normalization and skull strip functions.
So, if I edit the header of each nifti file so that the slice thickness isn't 0,
recon-all -autorecon1 should work?

Thanks.

Best,
Lisa

The problem is that the slice thickness is 0. BTW, I don't know what you are planning to do with this in freesurrfer, but it's not going to work with only one slice.
