Hi, I had a subject with immense scanner movements in the scanner (10 mm+). So, I was curious whether using checkreg for two images from first and last session (before realigmen) I can see the missaligment. Though, it was not very apparent by eye, I noted that the same point it two images landed in different voxels coordinates (attached). In Z axis (the strongest movement) the divergence was ~3 slices, which makes sense since my slice thickness was 2.4 mm. Is this coordinates divergence really manifestation of the scanner movements? For realigned images the voxels coordinates are identical, but does it imply that images were fully realigned? Thanks, John
