Hi Swaroop, I am not really sure what is going on here. Is there any chance you could provide me with a dataset and code to try to reproduce the issue? At some point the way these voxel selection results were stored were changed, though I tried to make it backwards compatible. Would it be possible for you to re-compute the voxel selection results? best, Nick
