I’m working with macOS operating system on mac with M1 processor.  
I’m having problems in order to obtain a meshDxx.vtu (starting from 2 files meshR.vtu and Dxx.mhd) which associates the values of the tensor built in Dxx.mhd to the meshR.  
Following a guide given to me, I ran the following command:  
`vmtk myvmtkmeshDlabeling -ifile meshR.vtu -diffusionmapfile Dxx.mhd -diffusionarray "Dxx_labels" -ofile meshDxx.vtu`

I get the following output:

```auto

It seems to be processing but I believe there is some problem as it doesn’t seem to have an end and I cannot obtain this file. How can I solve this problem?

`myvmtkmeshDlabeling` isn’t a script shipped with vmtk, so not quite sure what you are attempting to do or what the problem could be.

I know that it is a vmtk command which takes in input a refined mesh (meshR.vtu), a component of the DTI and the name of the array to be associated with the mesh cells, and returns a new mesh that has, associated in each cell, the value of the chosen component of the diffusion tensor.In the guide I am using it is indicated that it is an alternative vmtk command to the python script label\_D.py
