Voxel mask is in the wrong location

When I run OspreyCoreg the voxel mask is placed in the wrong location:

Here is where the voxel mask should be:
This is after I select add overlay and open the raw svs file, and the voxel is shown in red here:

I’m not sure why Osprey (or SPM?) places the mask in the wrong place- and it only happens to two particiapants. Any advice on why this could be happening?

Hi Julia,
is it measured with a Siemens Scanner? Which version?
Have you used fixed table position?
What I could most likely imagine is that there has been a change in the table position and this is stored in a different position than the one used in the Osprey script.

Best,
