Operating system: Windows 10 Pro Slicer version: 4.11.20210226 Hi, I did some segmentations on a TIFF file and obtained the 3D reconstruction of the structures. After some problems with the ruler bar (that I set after the segmentation), I tried to do a new segmentation with the same TIFF file, st…

@Andreza can you provide screenshots of what the Volume Information is for your master volume that you used for segmentation and your segment geometry. For volume information go to volumes module and expand Volume Information tab get a screenshot and paste. [image] For segment geometry, click thi…

Hi, it goes Volume information [image] And segment geometry [image]

As you can see, they do not match, which suggest to me that you modified the image spacing value in your master volume after you created your segmentation object, as opposed to before. So delete all the segmentation objects in your scene, right click on your volume and choose segment this, then pro…

Yes, as I said, I modified the pixel size information after the segmentation was done, which I think, it explains the pixeled ROI or green quadrates. I did more than 100 segmentations already. Because of this, I would use only the segmentations and their 3D reconstructions (without the ruler bar),…

You can use the method I described here to correctly scale your existing segmentations and your volumes. [image] Ruler in (orthographic) 3D view Support As you are observing, it is important to check that the imported image stack has the correct image spacing as the first …
