Hi Pernille,

The shift doesn't really effect any edits or processing you might be doing on the datasets. But if you want to get rid of it, on the tkmedit tools window, you can select View -> Anatomical Resampling -> Main Volume/Aux volume -> Slice.

Hi Pernille

here's a zoomed image of the subject you sent me. Is this what you see? I don't see any shift over the brainmask.mgz - it looks pretty accurate to me.

Hi After running several subjects (using trio siemens dicomfiles) with recon-all -all -nowmsa, we have observed an apparent shift of approximately one voxel to the left of the pial surface as compared to the brainmask.mgz in the TkMedit coronal view. This was observed in all of our subjects. Do you have any explanation for this - are there any corrections we need to do to avoid this?

Thanks, Pernille
