Different coordinate systems when exporting stl files from 3D Slicer to matlab

[pieper (Steve Pieper (Isomics, Inc.))]

Hi Clara -

This page describes the way Slicer manages coordinate systems:

https://www.slicer.org/wiki/Coordinate_systems

With the most recent versions of Slicer (the current nightly) there’s also an export widget that lets you chose the space for the exported models:

Save segmentation directly to STL or OBJ files

We often received questions about how to export segmentation to STL file for 3D printing. We’ve added a simplified, dedicated tool to make this step easier. 1-minute demo video: [Export Slicer image segmentation to STL or OBJ file] Main features: Export STL file: each segment as a separate file or all segments merged into a single mesh Export OBJ file: all segments are saved in one file, segment colors and opacities are preserved Export all or visible segments only Coordinate sy…

Hope that helps,
