Thank you for all the help. I've done 1, 2, 3. It's printing the array for the tumor volume with the right dimensions. The image background is black so a...

@larsoner I'm hoping you may be able to help troubleshoot. I drew a 3d tumor volume on 3d slicer and saved as nrrd (attached here) [tumor.nrrd.zip](https://github.com/mne-tools/mne-python/files/9006228/tumor.nrrd.zip) . @alexrockhill helped me...

@alexrockhill i tried the same code with a larger tumor volume. [bigtumor.nrrd.zip](https://github.com/mne-tools/mne-python/files/9014186/bigtumor.nrrd.zip) I wondered if there could be an issue if the volume is not 100% filled in/solid. Like one...

@alexrockhill that worked! I simply replaced > verts, faces = _marching_cubes(data, [1], smooth=0)[0] with > verts, faces, normals, values = measure.marching_cubes(data, 0) now time to add it to the existing...

@alexrockhill Glad you are able to see it! I got the tumor on the same plot of the brain using brain._renderer.mesh() In order to work on aligning it I was...

@alexrockhill good idea. I'll work on that this afternoon!

here is the 3D slicer example MRI (nii.gz) and tumor volume (nrrd) for your reference @alexrockhill I can work with caleb to do the free surfer reconstruction on this example...

@alexrockhill the example is provided by 3D slicer when you download https://www.slicer.org/wiki/SampleData Tutorial file won't upload it's too large so i'll email it.

@alexrockhill I'll have to shorten it

uploaded privately to youtube because even with low quality the file was too large. https://www.youtube.com/watch?v=aZthPcASknI @alexrockhill
