Hello Guys, I am trying to convert an stl file to nifti using Dicer. I found the following: Conversation: Converting .stl files to binary label maps in .nii format using Python I have tried to follow the instructions of Donnie Cameron. However, when I give the command: seg.SetReferenceImageGeom…

See complete example in the script repository .

Dear Andras, Thanks for your reply. I have tried to follow the script for converting stl to TIFF images but still get error messages. In particular, the command inputModel.GetBounds(bounds) returns the error message: Traceback (most recent call last): File "<console>", line 1, in <module> Att…

The variable inputModel should contain a vtkMRMLModelNode and not a boolean

Dear Csaba, The variable inputModel was set according to the script as: inputModel = slicer.util.loadModel(inputModelFile) Where inputModelFile was my path to my stl file. And that created the boolean object. Hence, I think that there is a problem in setting the stl as a vtk object in Slicer. …

At this point this is regular Python programming. If you see the documentation of the function you use you’ll see why you get a boolean: >>> help(slicer.util.loadModel) Help on function loadModel in module slicer.util: loadModel(filename, returnNode=False) Load node from file. :param…

The API is changed in Slicer-4.11. By default we don’t use Boolean flag to indicate error anymore, but raise an exception instead. This allows simpler syntax of inputModel = slicer.util.loadModel(inputModelFile). I would recommend to update to latest Slicer stable or preview release.

Thanks.

Using the syntax:

[Status, inputModel] = slicer.util.loadModel(inputModelFile, returnNode=True)

indeed solved the problem.
