Operating system: windows  
Slicer version: 5.0.3  
Expected behavior: Add an input image to extract a skeleton from it.  
Actual behavior: I can’t select an image from my computer when clicking on “SelectLabelMapVolume”. Why?

From the screensgot, it is not clear whether that’s a segmentation or a 3d model. Either way, for to module work you need to convert them to a label map.

İf it is segmentation, right click on it and choose export label map. İf it is a 3d model, first right click and select convert “segmentatition” and once it is converted to a segmentatition object, repeat the previous step of exporting to a label map.
