Dear experts,

Is there any way I can calculate the cortical thickness based on gray matter and white matter binary images from other software. 

I mean I have a image in native space with white matter voxels labelled as 10 and gray matter voxels labelled as 5.

Is there any way I can manage to calculate the cortical maps from this image using freesurfer?

Thanks a lot!

Best,

Yuanchao Zhang
