Hi Bruce:

Thanks you very much for your answer... And, how can I get the volume of the new segmentation of the CC that I got with mri_cc command ?...

Sincerely,

Gonzalo Rojas Costa

I mean that if the volume is rotated in any 2d slice it can look as if only some of the cc is properly labeled, even if the full 3d labeling is correct On Tue, 15 Mar 2011, Gonzalo Rojas Costa wrote:

Hi Bruce;

I don't understand why you said that in 3D the labeling is usually correct... ???...

Hi Gonzalo

mri_cc computes the optimal rotation. If the patient's head is not straight this can make it look like an inconsistent labeling, but in 3d it usually is correct.

Hi:

The CC_Posterior, CC_Central, etc, volumes in "aseg.mgz" are the complete CC volume, or it includes only some sagital slices ?...

How can I meassure the CC volume for some sagital slices only (5 in total for example) ?... When I tried using "mri_cc" I got an error (for example) in the case that the patient is slightly rotated (freesurfer segments only one section of the CC as CC and the other as WM)...
