[Freesurfer] question about tksurfer

Hello,

I am testing the output of some data I ran through the reconstruction process. While attempting to view the rh.sphere volume with the rh.curv overlay, I only could see the red lines, not the green lines. I noticed that I had to adjust the settings (view--configure--curvature display). I had to change the value of the threshold midpoint to .2 and the threshold slope to 3.5. Only then could I see both. Is this normal, or maybe is something wrong...all of the processes said they finished without error.

Thanks.

Adam
