Operating system: Ubuntu 22.04  
Slicer version: 5.0.3  
Expected behavior: calculation of maxEigenValueProjectionX ,Y ,Z  
Actual behavior: none…

Hello Community,  
I want to calculate ALPS index from a DTI-MRI sequence…  
I use Slicer 5.0.3 and the DIFFUSION TENSOR SCALAR MAPS module gives me only maxEigenValue. But I need the projections in x, y, z.  
How is it possible to generate this 3 maps?

There is a tutorial online where DIFFUSION TENSOR SCALAR MAPS module calculates maxEigenValueProjectionX ,Y ,Z, but this is from 2012 so it is from an old slicer version, and I can’t get it here on my work pc… ;(  
thank you for your help.  
Jürgen
