[Freesurfer] Extracting surface normals using mri_surf2surf

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.
