Hi all, I want to segment the hippocampus into head/body/tail in itk SNAP using the hippocampus mask that I create from the result of recon-all segmentation. My question is, are the T1.mgz and aseg.mgz files in the native space of the image or in the atlas space? I know the voxel size is different (1x1x1 mm) from the original voxel size (0.49x0.49x0.45), but I want to know if the original images are registered to a common atlas space or just resampled to a different voxel size. The reason I'm asking this, is because I'm doing a group study and I want to make sure all my subjects are in the same space so that the segmentation I do is accurate for all.
