Operating system: OS X MAC  
Slicer version: 4.8.1  
Expected behavior: I expected ShapePopulationViewer to show up under the Surface Models tab once I downloaded the Model to Model Distance extension module  
Actual behavior: I downloaded the extension successfully and I was able to create the color map but when I went under Surface Models there was no tab for ShapePopulationViewer and so I could not actually create the color map.

Shape Population Viewer will show up if you download Shape Population Viewer extension. It may be also bundled in [SlicerSALT](http://salt.slicer.org/) installation packages.

Note that Slicer-4.8.1 is more than a year old. We only support latest stable (Slicer-4.10) version, and some fixes and features (such as example Shape Population Viewer) may only be available in latest nightly versions.

Thank you for your help! I downloaded Slicer 10.0 and I still can’t find Shape Population Viewer as an extension. I can download it as a separate file but I can’t figure out how to get it to work with Slicer. I am able to download the MeshStats and ShapeQuantifier extensions but not shape population viewer and all I need to do is create a color map. Any suggestions are welcome! Thanks again!

I can confirm that the ShapePopulationViewer extension is available for download from the Extension Wizard within today’s nightly Slicer 4.11.0-2019-01-07.

There is an error building the extension for Slicer 4.10 because it is looking for a branch that no longer exists. @jcfr I see in [NIRALUser/ShapePopulationViewer #33](https://github.com/NIRALUser/ShapePopulationViewer/issues/33) that you encouraged a change to this branch name. Do you know what tag can be used so that ShapePopulationViewer can work for Slicer 4.10 stable as well?
