As you are observing, it is important to check that the imported image stack has the correct image spacing as the first step of your workflow. Since everything else (segmentations → models → measurements) are all dependent on this piece of information. This is especially true if you importing these images from 2D formats like PNG/TIFF etc which doesn’t preserve this information. You don’t have to redo the segmentation but it will take you a few steps to get them in correct alignment. This is wh…
