I’m looking to obtain a file with a 3D cartesian grid containing the segmentations I’ve created. I’ve worked a bit with the Segment Mesher module but have not found a way to export a simple cartesian grid of a prescribed size. Is this possible to do in 3D slicer or is there some other software I could use to do this? It seems like a simple task but I haven’t found a good way to do it.
Segmentation is saved by default in a 3D Cartesian grid (image volume). You can change the segment geometry (origin, spacing, axis directions) by clicking on the button in Segment Editor next to the master volume selector.
By default segmentation is saved into a 4D volume file (each 3D volume contain a binary labelmap), but you can export it into a single 3D volume if you export the segmentation to a labelmap node first.
