no, you should use mri_convert -c to "conform" them. tkmedit is only guaranteed to work with volumes that have been put through this process.

So my images are 256x256x192 x 1.0mm. One of them works and the other doesn't. Should I add blank slices to bring it to 256?

what volume are you selecting them on? Make sure that it has been "conformed" - that is, that it's 256^3 and 1mm isotropic. On Tue, 1 Aug 2006, Faden, Eric (NIH/NIMH) [F] wrote:
I am currently running 3.0.3 on RedHat EL v4. Whenever I load up a brain and try to draw control points I can see a little green cross about 1 voxel down and to the right of the red cross, but as soon as I move the red cross they vanish and I can no longer see them. FreeSurfer is saving the points to tmp/control.dat though they just do not seem to display. Any ideas why?
