the orig.mgz is also changed to 1 byte/voxel. The norm.mgz is in the same space, but with the skull removed and the subcortical intensity normalization run on it. All the volumes in fact in the mri dir except rawavg.mgz are in the same coords

I see. To clarify. orig is the conformed version of the original input file,
which means just sampling to 1 mm as needed, and cropping to 256 matrix.
norm.mgz has some intensity corrections, but does not include spatial
changes.

I had read http://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat
and I thought that maybe that spatial warping was involved beyond resampling
to the original dimensions/resolution to get to  "native space". This
simplifies things greatly. Thank you both.

      Hi Josh,

      there are no spatial transforms to go from orig to norm. They
      are in the same space.

            Hi Doug,

            Is a standard 12 affine registration sufficient to
            get a subjects structural
            (in a different orientation) into the same space as
            norm.mgz, or will I need
            some non-linear registration? Basically, what kind
            of transforms are applied
            to go from orig to norm?

                  That was in fact what I decided to do.

                  Can you compute the registration between the
