Operating system: Windows  
Slicer version: 4.10  
Expected behavior: Segment and export as .obj file  
Actual behavior: Can’t segment. Also can’t load as binary labelmap.

I have some microscopy data which has effectively already been segmented into a binary TIFF stack. I want to export the fluorescent regions as an .obj file so I have a 3D model.

I’m not able to select any regions of the data for further segmentation (no threshold range can be selected). I have also tried importing the data as a binary labelmap, but it does not appear to work - I have looked in the Data and Segmentation modules but found no files there.

What am I doing wrong?

If this is rgb data you can use the Vector to Scalar Volume module to convert it, then you should be able to use it with the Segment Editor.
