converting .stl to .nrrd

Is there a way to convert my .stl to a .nrrd?

I am able to import my stl into Slicer through Import>Models which supposedly creates a Segmentation (though nothing appears on the screen) and then my export segmentation options are vtm.

Thanks!

You can use “Segmentations” module to export segmentation as Labelmap (“Export/import models and labelmaps” section), which you will then be able to save as NRRD.

Hello Fedorov,
How can I create one NRRD file that contein multiple segmentations.vtm
