Re: [Freesurfer] Control point failure - CA Normalize

Hi Mark

does the input to mri_ca_normalize look ok (the nu.mgz)? Is the talairach.xfm ok?

Hello freesurfers,

I am running into a problem during the "CA Normalize" sequence of autorecon-2. It looks like freesurfer is having a hard time creating control points based off the atlas I am using. The output is as follows:

"finding control points in <Left_Cerebral_White_Matter>...found  0 control points"

This repeated for the other various regions included in the atlas. The only control points found were "168 control points" in the "Right_Cerebral_White_Matter". Could this possibly be an alignment issue? If so, is there an easy way to check the alignment?

Thank you,

Mark
