[MINC-users] spatial location of voxels

Dear MINC users,
I was wondering what to what spatial location the MINC coordinates (both
voxel and world) refer to. Is that a vertex (which of the 8), the middle of
an edge, or the center of a voxel?
Furthermore, I was wondering whether there's a command or tool to extract
the exact voxel (and world) coordinates for certain conditional voxel
values (i.e. thresholds) in a volume. Of course the exact voxel coordinates
suffice, for world coordinate = voxel coordinate*step + start, but if
there's such a tool existing, it would come in handy. (The reason is that I
would like to compare some voxel coordinates from volumes that have been
registered, but have different voxel sizes.)
Thanks in advance,
Kuan Kho
