Hi Tina,

We don't usually visualize them together, so translations are kind of irrelevant for us. I don't have anything to translate them, but it would be easy enough to do in matlab (or Amira I would think, although I haven't used it)

Hello FreeSurfers,

I have inflated a couple surfaces less so that the gyri and sulci are more prominent on the surface using the parameters:

mris_smooth -a 70 -n 70 -nw ./subj/surf/lh.white ./subj/surf/lh.smoothwm

mris_inflate -n 5 ./subj/surf/lh.smoothwm ./subj/surf/lh.inflated

mris_curvature -w -a 70 -thresh .999 -distances 10 10 ./subj/surf/lh.inflated

Which seemed to do the trick, however, when I viewed the surfaces on the 3D surface generator Amira, I realized that inflating less caused the left and right surfaces to shift toward each other when viewed on the same coordinate system. The left and right surfaces must have been translated somewhere in the inflation process. How do I put them back into the correct coordinate space that the pial and white surfaces are? Thank you.
