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! Shengwei
