Hi FSL experts,

 I'm using tbss to deproject voxels on the skeleton to each warped subject. So tbss_deproject stage 1 was executed.

But I found that the number of voxels on the warped subject was sometimes smaller than that I chose on the skeleton, e.g. I picked 40 voxels on the skeleton and just had 38 or 39 voxels on the warped subject.

So what happened to the missing voxels and why? Anybody have the same situation before?

Any help is appreciated!
