Hi Daniel do you mean the white and pial surfaces? You can certainly compute the surface normals for them, or use mris_convert to do it:
mris_convert -n lh.white lh.white.normals.asc will compute and write out the surface normals (using an outwards-pointing convention) for the white surface to an ascii file cheers Bruce On Fri, 13 Nov 2015, Daniel Lindh wrote: > Hi, > I am looking for a way of figuring out the orientation vector of the neurons > within a voxel.
