You can create a new volume node as shown in this example: https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Create_a_new_volume
For creating a vector volume: use vtkMRMLVectorVolumeNode
instead of vtkMRMLScalarVolumeNode
and in AllocateScalars
use 3 components instead of just 1.
Thank you Andras! For some reason when I assign a volume to my new empty vector volume, the image is being rotated 180 degrees. The array of voxels for the volume is correct and so I’m confused why it is appearing as rotated. Let me know if you have any idea of why this is the case!
Expected output:
Actual output:
Slicer uses RAS coordinate system. If your image array is in LPS coordinate system (this is the most common) then you need to set imageDirections = [[-1,0,0], [0,-1,0], [0,0,1]]
.
Do you load the data from file? Why don’t you load them using standard image loading functions?
This works, thank you Andras!
