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?
