 # QuickAlign
-In research 3D imaging, often there is no fixed orientation in which samples are scanned consistently. For comparative purposes, it is often easier to bring these 3D specimen into approximately similar anatomical orientation to compare. If precision is required and necessary, this can be done by using the automated registration tools in Slicer and SlicerMorph, depending on whether the data is a volume or a 3D model. However, for simpler side-by-side comparison of two objects, **QuickAlign** module can provide a convenient alternative to align volumes, modules and landmarks (pointLists).

-Additionally, **QuickAlign** provides linking two landmarks sets in this orientation, so that point-to-point correspondences of dense landmarksets can be easily compared by selecting specific points which then gets highlighted in the linked dataset as well.

 Using sample data from SlicerMorph, this tutorial explains how to align two specimens that might be in different orientation and size side-by-side. To follow the rest of the tutorial, download both **Gorilla Skull Reference Model** and **Mouse Skull Reference Model** from the `Sample Data` module of Slicer. Save the downloaded zip files somewhere you can easily find, and unzip them.
