You can't use analyze for this because the number of vertices is a prime number. No dimension in an analyze file can exceed 32k. Usually, we get around this by dividing up the vertices across mutiple "slices", but this is not possible when the number of vert is prime. NIFTI inherited the same problem. Try using mgh instead.

Hi, All,
I am trying to extract the surface normal values using mri_surf2surf: %mri_surf2surf --s subject1 --hemi lh --sval-nxyz white --tval lh.white.surfn.img --trg_type analyze4d
The error mesage is : ...... Loading source data Extracting surface normals INFO: surfcluster: NOT fixing group surface area INFO: trgsubject = srcsubject Saving target data Reshaping 131441 (nvertices = 131441) ANALYZE FORMAT ERROR: nslices 131441 in volume exceeds 32768
I am using FreeSurfer v303. I tested the above command on the subjects inflated by old version of FreeSurfer, and I could get the surface normals. Anything wrong with the new inflation?
Thank you for your time.
